Sleeper is the third and final studio album by the Boston alternative band Tribe, released in 1993.

[3][4] The album was recorded and mixed at Blue Jay Recording Studio in Carlisle, Massachusetts, from December 1992 to January 1993.

The album yielded two singles, "Supercollider" and "Red Rover," the latter of which also yielded the band's second (and last) music video.

[5] The band performed "Supercollider" on Late Night with Conan O'Brien in January 1994,[6] marking the band's only ever national television appearance.

The Boston Globe deemed the album "an uneven effort, hampered by an often poor sound mix in which Janet LaValley's ... vocals are mixed too low, muting her power and rendering many lyrics inaudible.
