I always wondered if there was ever a solo album by an artist who was also part of their main band, but still ended up recording the album with the band... but it's specifically a solo album project. I.e. if Freddy Mercury had recorded Mr. Bad Guy with the other three members of Queen, with everyone recognizing it was going to be Freddy's solo album. In case something like that never happened, what are some solo albums utilizing at least two members from their main band? Preferably while they're still in the band but feel free to mention ones where they had already left the band (I believe some solo Beatles albums fit this category). One example I'm aware of is Steve Hackett's Voyage of the Acolyte, from 1975 and has his Genesis bandmates Phil Collins on drums and Mike Rutherford on bass, but no Tony Banks so it comes close at 3/4 of Genesis at the time performing on Steve's debut solo release.
