Quo is the seventh studio album by the English rock band Status Quo. Issued in May 1974, it features Francis Rossi, Rick Parfitt, Alan Lancaster and John Coghlan, and reached #2 in the UK. Like its predecessor Hello!, it consisted entirely of songs written or cowritten by the group. The only guest musicians were Bob Young and Tom Parker, who played harmonica and piano respectively on "Break the Rules".
The band believed the opening "Backwater" to be the most suitable candidate for a single. However, the only track released as a single was "Break the Rules", in April 1974. It peaked in the UK at #8.
The album is regarded as one of their heaviest, possibly due to the influence of bassist Alan Lancaster, who cowrote six of the eight tracks. "When we wrote 'Drifting Away'," recalled Parfitt, "it sounded so, so heavy. That rhythm was constant, right in your face. It was just such a turn-on. That's where my head was at back then. You know: just let it fucking rock."
The UK LP contained a gatefold insert with a picture of the band playing live on one side, and the lyrics on the other. The sleeve-art was by British artist Dave Field.
