The Dark Side of the Moon is the eighth studio album by English progressive rock group Pink Floyd, released in March 1973. The concept album built on ideas explored by the band in their live shows and earlier recordings, but it lacks the extended instrumental excursions that characterised their work following the departure in 1968 of founding member, principal composer and lyricist Syd Barrett. The Dark Side of the Moon's themes include conflict, greed, the passage of time and mental illness, the latter partly inspired by Barrett's deteriorating mental state.

When John Lee Hooker met with The Groundhogs it was blues magic. When he traveled to England, he enjoyed playing live with the Hogs as his back up band. Originally, the father of the British blues John Mayall had the job sewn up, until Eric Clapton quit his band and then plans changed. Much to the delight of guitarist Tony McPhee, the Hogs were in.
