Well, when he left UFO he formed the Michael Schenker Group.
His first album is a s/t and second is titled MSG.
He sacked Gary Barden for Graham Bonnet for his third album Assault Attack. (produced by Martin Birch..sounds incredible)
He brought back Barden for Built To Destroy (which I think you would love.)
After a few years off, he resurfaced in 1987 with Robin McCauley and formed the McCauley Schenker Group (MSG
)
They released 3 albums. The mid 90's through the 00's saw him release a number of Michael Schenker Group albums, with numerous vocalists. These are all kind of spotty. Some good stuff though.
In 2000, he released Adventures Of The Imagination, which is an excellent instrumental album. Open Gate from F&M is from this. He has a number of instrumental albums, and a bunch of cool acoustic ones titled Thank You. I believe there are 4 of these.
His last three albums have been under the Michael Schenker's Temple Of Rock monicker. The first one sucks, but the last two, 2013's Bridge The Gap, and this year's Spirit On A Mission are two of the best albums he's done since his classic early 80's material.
