Bachman–Turner Overdrive

Bachman–Turner Overdrive (frequently known as BTO) is a Canadian rock group from Winnipeg, Manitoba that's best known for its series of five Top 40 albums and six Top 40 singles in the 1970s, selling over 7 million albums in that decade alone. Overall, the band has sold nearly 30 million albums worldwide. Many of their songs, including "Let It Ride", "You Ain't Seen Nothing Yet", "Takin' Care of Business", "Hey You" and "Roll On Down the Highway", still receive play on classic rock radio stations. BTO fans are affectionately known as "gearheads" (derived from the band's gear-shaped logo).

The precursor to BTO was the band Brave Belt, which was formed in 1970 by Randy Bachman and Chad Allan (both of The Guess Who), Robbie Bachman and Fred Turner. An original form of the group included musician Keith Emerson of The Nice (and later of Emerson, Lake & Palmer), but he was dropped due to illness. After two moderately successful Brave Belt albums came out, Allan was replaced by Tim Bachman, the third of the Bachman brothers, and the band changed its name to Bachman-Turner Overdrive.
