Bachman–Turner Overdrive, often abbreviated as BTO, is a Canadian rock group from Winnipeg, Manitoba, that had a series of hit albums and singles in the 1970s, selling over 7 million albums in that decade alone. Their 1970s catalogue included five Top 40 albums and six US Top 40 singles (eleven in Canada).
The band has sold nearly 30 million albums worldwide, and has fans affectionately known as “gearheads” (derived from the band’s gear-shaped logo). 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 stations.
The original lineup consisted of Randy Bachman (lead guitar, lead vocals), Fred Turner (bass guitar, lead vocals), Tim Bachman (guitar, vocals) and Robbie Bachman (drums). This lineup released two albums in 1973. The second and most commercially successful lineup featured Blair Thornton (lead guitar), in place of Tim Bachman. This lineup released four albums between 1974 and 1977, including two that reached the Top 5 in the U.S. pop charts, as well as the band’s only U.S. No. 1 single (“You Ain’t Seen Nothing Yet”). Subsequent lineups enjoyed only moderate success.
