NRBQ – The New Rhythm and Blues Quartet - is an American rock band founded in 1967. It 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. Its current membership comprises the quartet of pianist Adams, bassist Casey McDonough, guitarist Scott Ligon, and drummer John Perrin. Some of the more notable members in the band's long history are guitarists Al Anderson and Johnny Spampinato; drummers Tom Staley and Tom Ardolino; and vocalist Frank Gadler. The band's music is a blend of styles from rockabilly to Beatles- influenced pop to Thelonious Monk-inspired jazz. They have attracted fans as diverse as Bob Dylan, Paul McCartney, Elvis Costello, Keith Richards, The Replacements, John Sebastian, Dave Edmunds, Ira Kaplan and Penn & Teller. NRBQ songs have been performed by Bonnie Raitt, Los Lobos, and Dave Edmunds among others. 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. NRBQ allowed several of their songs to be used on The Simpsons, including "Mayonnaise and Marmalade", written specifically for the show. NRBQ has a following from years of live shows. The band has been known to perform without a set list which makes the band, in the words of AllMusic's Mark Deming, "a stellar and wildly unpredictable live act." In addition to its own compositions, the band performs a broad range of cover material and audience requests.
