[1] McKasty gained recognition for his work with notable artists such as Devo, Organized Konfusion, Kwamé, Queen Latifah, Biz Markie, Ultramagnetic MCs, Rahzel, and Eric B & Rakim.

[1] He developed an interest in music from his older brother Michael, who was a guitarist, and Tim, who worked as a recording engineer at 1212 Studio in Queens.

[4] According to Paul's middle school friend TeQnotic, he was an already gifted artist and bass guitar player in junior high.

[7] Musician and producer Moogy Klingman, who was a founding member of Todd Rundgren’s Utopia, helped the group mix and master the album.

[6] After the group disbanded, Paul started making beats in a bedroom studio at his family's Rosedale, Queens house.

[6] Paul eventually moved his production setup out to his garage and was later introduced to rapper Michael Deering, aka Mikey D, by Eddie and Will.

[6] On "Bust A Rhyme Mike", Paul showed an advanced understanding of the E-mu SP-12 sampler, as he recorded Mikey D making three different percussion sounds with his mouth and wove them together into a beat.

[6] He also impressed Mikey D with his ability to take vocal sounds from beatboxer Rahzel, change their pitch, then turn them into a fluid bassline on "I Get Rough".

Paul C's best-known work is on Ultramagnetic MC's 1988 classic debut album Critical Beatdown[10] and the non-album singles the group released between 1988 and 1989.

He has only one credit as a producer on Critical Beatdown, for the track "Give the Drummer Some", but according to group members Paul C was responsible for the overall sound of the album.

Paul C also worked for many other artists including Grandmaster Caz, Super Lover Cee and Casanova Rud, Stezo and Rahzel.

Paul played an instrumental role in the making of Super Lover Cee and Casanova Rud's Girls I Got ’Em Locked album, which reached #77 on the Billboard charts and sold 425,000 copies worldwide.

"[10] He overheard a recording session of a new local group named Simply Too Positive and offered to produce its entire demo.

[6] Besides working with the cream of the crop in hip hop, Paul also did two remixes for the American rock group Devo with the songs "Disco Dancer" and "Baby Doll".

[20] Though many notable producers such as The Bomb Squad, Easy Mo Bee, Lord Finesse, Large Professor, Pete Rock and Ski used the sampler, Paul is credited as one of the early innovators of chopping with it.

[21] Large Professor credited Paul C for helping him move from "pause-tape" production to making more elaborate compositions with the 1200, saying "He took me out of that tape deck era.

It’s like letting my man know I’m still focused.”[1] Engineer and producer Nick Hook obtained McKasty's SP-1200 from Merry Jane editor-in-chief and A&R/producer Noah Rubin.

"Collaborator and friend CJ Moore explained his unique drum manipulation techniques that he used to engineer Stezo's Crazy Noize album in an interview.

Then went around and got the hi-hats and re-sampled them and did all kinds of little things to it.”[27] According to Large Professor, Paul would also double time certain elements of his beat to make sure they were "tighter than average.

"[22] In addition to chopping, drum programming, and panning, Paul is also noted for bringing a sophisticated level of musicality to his production.

[29] His murder was featured on America's Most Wanted,[10] leading to the arrest of Derrick "Little Shine" Blair in Fayetteville, North Carolina.

[29] A witness who saw two men leave McKasty's house the night of the murder identified Blair in a lineup four months prior to his arrest on Tuesday, February 13, 1990.

[30] The arrest took place after someone saw a re-enactment of McKasty's murder, which appeared on WNYW-TV's New York's Most Wanted and the Crime Stoppers television show in Fayetteville, and contacted authorities to tell them Blair's whereabouts.

a spokesman for the Queens District Attorney's office, a second suspect remained at large after authorities found Blair.

[29] The police were unable to determine a motive for McKasty's murder at the time of Blair's arrest and he faced a maximum jail sentence of 25 years to life.

[10] They were later cleared of any wrongdoing, but the implication that Super Lover Cee and Casanova Rud were involved with Paul's death was damaging to their career.

[6] Large Professor spoke about the difficult time after Paul's death where several collaborators and friends were suspects, saying "He got shot up and that’s all I knew.

[27] Super Lover Cee and Casanova Rud, who were working on a sophomore album with Paul at the time of his murder, also recorded substantial material with him that was never released.

[36] Other hip hop producers such as Cut Chemist,[10] Domingo,[37] Madlib,[38] Pete Rock,[10] and DJ Shadow[39] cite Paul C as an influence.

[10][11] Kool Keith credits Paul's honest criticism of his raps for making him pay more attention to his delivery and pronunciation.
