NRBQ is an American rock band founded by Terry Adams (piano), Steve Ferguson (guitar) and Joey Spampinato (bass). Originally the "New Rhythm and Blues Quintet", the group was formed circa 1965. Adams disbanded it for a time, and the group re-formed in 1967. 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.

From 1974 to 1994, the band included pianist Adams, bassist Spampinato, guitarist Al Anderson, and drummer Tom Ardolino. This is considered the classic lineup of the group. Its current membership includes Adams, bassist Casey McDonough, guitarist Scott Ligon, and drummer John Perrin. Other members in the band's long history include guitarist Johnny Spampinato; drummer Tom Staley, and vocalist Frank Gadler.
