Bachman-Turner Overdrive

Bachman–Turner Overdrive 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 catalog included five Top 40 albums and six Top 40 singles. The band has sold nearly 30 million albums worldwide, and has fans affectionately known as "gearheads" (derived from the band's gear-shaped logo).
