McAuley Schenker Group was a multi-national rock band based in Los Angeles featuring core members Robin McAuley (vocals) and Michael Schenker (guitar), a successor to Schenker's earlier band Michael Schenker Group. McAuley was initially contacted to replace singer Gary Barden in MSG. However, the strong partnership immediately formed between McAuley and Schenker led to the change of the name from Michael Schenker Group to McAuley Schenker Group, retaining the same initials of the previous band MSG.

Michael Schenker is a German guitarist. He played in the rock band UFO and leads the Michael Schenker Group (MSG). He was an early member of the hard rock band Scorpions, a band co-founded by his elder brother Rudolf Schenker. In the mid-1970s, Schenker joined UFO, playing lead and rhythm guitar. He left the band in 1978 to briefly rejoin Scorpions for the recording of Lovedrive, and then to form MSG. He has rejoined UFO three times, producing an album each time. Schenker continues to perform and record. He has been called "a legendary figure in the history of metal guitar."
