The 5uu's were an American avant-rock group founded in Los Angeles, California in 1984 by drummer-composer Dave Kerman. The group released their first album in 1986 and recorded a second in 1988 with Motor Totemist Guild, a similar band from the area. The two groups merged in 1988 to form U Totem and made two albums. When U Totem split up in 1994, the 5uu's reformed and went on to make two more albums. In 2000 the band became known as Dave Kerman/5uu's and released a further two albums under this name. After a long pause, an album, The Quiet In Their Bones was released in 2022.
