NRBQ is an American rock band founded by Terry Adams (piano), Steve Ferguson (guitar) and Joey Spampinato (bass).

[1][2][6] The quartet is known for its live performances, containing a high degree of spontaneity and levity, and blending rock, pop, jazz, blues and Tin Pan Alley styles.

[8] Its current membership includes Adams, bassist Casey McDonough, guitarist Scott Ligon, and drummer John Perrin.

Other members in the band's long history include guitarists Kenny Sheehan and Johnny Spampinato; drummers Tom Staley, Conrad Choucroun, Bobby Lloyd Hicks and Joe Camarillo; and vocalist Frank Gadler.

NRBQ began in late 1965 as a rehearsal band in the Shively, Kentucky, home of brothers Terry and Donn Adams, and they appeared on stage for the first time in 1966.

In late spring of 1966, guitarist Steve Ferguson was invited to join NRBQ after he quit Mersey Beats USA (no relation to the Liverpool group who recorded "I Stand Accused").

[1] After playing a few live dates in Louisville, Jimmy Orten (Soul Inc) was recruited on bass and vocals and the band left for Florida in late 1966.

[1][9] By August, the NRBQ was Adams (keyboards), Ferguson (guitar), Spampinato (bass) and Frank Gadler (vocals) from The Seven of Us, and Tom Staley (drums).

Their self-titled debut album was released that year, with songs by both Eddie Cochran and Sun Ra, and a number of similarly wide-ranging originals.

The shows featured every former and current member of the band, as Ferguson, Gadler, Staley, Sheehan and Anderson returned for an NRBQ reunion.

In March 2011, Adams posted an open letter to fans announcing that with the release of the upcoming album, Keep This Love Goin', this lineup would take on the NRBQ name.

In July 2013, NRBQ toured with drummer Joe Camarillo of The Waco Brothers and Hushdrops, where he recorded two songs on the Brass Tacks album: "Greetings from Delaware" and "I'm Not Here".

[1][7][10][3][2][12][4][9][6][5] They have attracted fans as diverse as Bob Dylan, Paul McCartney, Elvis Costello, Keith Richards, The Replacements, John Sebastian, Dave Edmunds, Yo La Tengo and Penn & Teller.

[5] Also, the group served as the unofficial "house band" for The Simpsons for the season 10–12 period in which NRBQ fan Mike Scully was head writer and executive producer.

The band always performs without a set list which makes them, in the words of AllMusic's Mark Deming, "a stellar and wildly unpredictable live act.
