The Wrecking Crew, also known as the Clique and the First Call Gang, was a loose collective of American session musicians based in Los Angeles who played on many studio recordings in the 1960s and 1970s, including hundreds of top 40 hits.

[5] Los Angeles was then considered the top recording location in the United States; consequently, studios were constantly booked around the clock, and session time was highly sought after and expensive.

[10] The talent of this group of "first call" players was used in almost every style of recording, including television theme songs, film scores, advertising jingles and many genres of American popular music from the Monkees to Bing Crosby.

[26] Douglas helped him corral the backing unit, which included Pohlman, guitarists Roberts and Tommy Tedesco, pianist Al De Lory, upright bassist Jimmy Bond, and Hal Blaine on drums.

[26][27] With them, Spector went on to produce other records by the Righteous Brothers ("You've Lost That Lovin' Feelin'", "Ebb Tide", and "Unchained Melody") and Ike and Tina Turner ("River Deep – Mountain High").

[26][nb 1] After Spector, the Wrecking Crew worked with dozens of producers, such as Brian Wilson, Terry Melcher, Lou Adler, Bones Howe, Jimmy Bowen, and Mike Post.

[28] As side players, they were teamed with artists as diverse as Jan & Dean, Bobby Vee, Nancy Sinatra, the Grass Roots, Simon & Garfunkel, Glen Campbell, the Partridge Family, David Cassidy (in his solo work), the Carpenters, John Denver and Nat King Cole.

"[30] Brian Wilson of the Beach Boys produced and co-wrote many of his band's most famous tracks and used the Wrecking Crew's talents extensively in the mid-1960s, including on songs such as "Help Me, Rhonda", "California Girls", and "Good Vibrations" as well as the albums Pet Sounds and Smile.

[35][34] Members of the Wrecking Crew served as "ghost players" on the first single by the Byrds, "Mr. Tambourine Man", because Columbia Records—namely, producer Terry Melcher—did not feel that the group (except for Roger McGuinn, who played guitar on the single) were seasoned enough to deliver the kind of perfect take needed, particularly in light of the limited time and budget allocated to the newly signed and unproven group—on a label that was only just beginning to embrace rock.

[46] Rick Nelson used many Wrecking Crew members in various combinations, mostly during the mid-1960s, including Earl Palmer, Joe Osborn, James Burton, Tommy Tedesco, Howard Roberts, Billy Strange, Al Casey, Dennis Budimir, Glen Campbell, Don Randi, Mike Melvoin, Ray Pohlman, Chuck Berghofer, Victor Feldman, Frank Capp, and Jim Gordon.

[48] Originally a guitarist, she began doing session work in Los Angeles in the late 1950s, playing behind Ritchie Valens on "La Bamba" and in the 1960s becoming a regular contributor on Phil Spector's recordings as well as on Beach Boys songs, such as "Help Me, Rhonda" and their subsequent Pet Sounds and Smile LPs.

[54] Joe Osborn played bass on numerous Wrecking Crew-backed songs, such as Glen Campbell's "By the Time I Get to Phoenix", the Mamas & the Papas' "California Dreamin'", Richard Harris' "MacArthur Park", and the 5th Dimension's "Up, Up and Away".

[56][57][58] Drummer Earl Palmer contributed to a handful of hits in the 1960s with the Wrecking Crew, including Phil Spector-produced tracks such as Righteous Brothers' "You've Lost That Lovin' Feelin'" in 1964, and Ike and Tina Turner's "River Deep – Mountain High" in 1966.

[62][18][63][nb 3] Though he had played primarily big band and jazz, he took a job in Tommy Sands' rockabilly group in the late 1950s, discovering a newfound appreciation for rock and roll, which by the beginning of the new decade led to session work in Los Angeles studios, where he became acquainted with Earl Palmer and saxophonist Steve Douglas.

1 hits, such as "I Got You Babe" by Sonny & Cher, "Mr Tambourine Man" by the Byrds, and "Strangers in the Night" by Frank Sinatra, as well as numerous others and has been mentioned by Drummerworld as perhaps the most prolific recording drummer in history.

[17][67] Jim Gordon began as an understudy of Blaine, but with the passage of time emerged as a first call player in the Wrecking Crew, playing on parts of the Beach Boys' Pet Sounds album and on hits such as "Classical Gas" and "Wichita Lineman".

[71][58][72] Gary Coleman played vibraphone and a variety of percussion instruments and contributed to works such as the soundtrack of the musical Hair and Simon & Garfunkel's Bridge Over Troubled Water album.

[79] Tommy Tedesco, born in an Italian family in Niagara Falls, New York, was another one of the Wrecking Crew's most renowned guitarists, playing along with Pitman on "Be My Baby" and "The Little Old Lady (from Pasadena)", as well as on the Champs "Limbo Rock".

[84][85][86] Though Glen Campbell became better known as a highly successful country music artist in his own right, he played guitar in the Wrecking Crew during the 1960s and appeared along with them on several of the Beach Boys' classics of the period such as "I Get Around" and "Help Me Rhonda".

[88][nb 6] Campbell enlisted the Wrecking Crew as a backup unit on many of his own solo records during the 1960s, such as on "Gentle on My Mind", and on two songs written by Jimmy Webb, "By the Time I Get to Phoenix" and his single "Wichita Lineman".

[98][99] Jim Horn played both saxophone and flute, and contributed parts to numerous tracks with Wrecking Crew, such as in the Righteous Brothers' "You've Lost That Lovin' Feelin'" and Frank Sinatra's "Strangers in the Night".

[102] Nino Tempo, who along with his sister Carol (under her stage name April Stevens) had scored a U.S. number 1 hit song in 1963, "Deep Purple", was also a member of the Wrecking Crew and played saxophone in the Ronettes' "Be My Baby" and later appeared on John Lennon's Rock 'n' Roll album.

[105] On trombone were Richard "Slyde" Hyde, Lew McCreary, and Dick Nash [105][106] and on trumpet Bud Brisbois, Roy Caton, Chuck Findley, Ollie Mitchell, and Tony Terran.

In the aftermath of the recent Bobby Kennedy and Martin Luther King, Jr. slayings, the bloody Tet Offensive in Viet Nam, and the ever-growing level of campus unrest at universities around the country, Top 40 radio gradually began to lose step with the times.

That was the unfair, mathematical irony of the whole equation; the Wrecking Crew had just played their hearts out on an all-time award-winning hit, yet its very success contributed toward a drop in the total number of songs making it on the air.

[116] Younger session players such as Larry Carlton, Andrew Gold, Danny Kortchmar, Waddy Wachtel, Russ Kunkel, Jeff Porcaro, Leland Sklar, and Jim Keltner had a more contemporary sound, better-suited to the changing musical tastes of the decade.

Eventually, drum machines would become the norm, which could be specially programmed to keep beats in place of a drummer or be used for click tracks played in musicians' headphones, making it easier to overdub or re-record any part in-synch and achieve a more uniform and consistent tempo.

[123] According to guitarist Bill Pitman, "You leave the house at seven o'clock in the morning, and you're at Universal at nine till noon; now you're at Capitol Records at one, you just got time to get there, then you got a jingle at four, then we're on a date with somebody at eight, then the Beach Boys at midnight, and you do that five days a week ... jeez, man, you get burned out.

Some members, such as Carol Kaye, Tony Terran, Gary L. Coleman, Earl Palmer and Tommy Tedesco, switched to television and motion picture soundtrack work.
