I have a few that I love. some would be:
Nick Cave and the Bad Seeds
Incubus
Supertramp
Captain Beyond (the self titled album is fantastic)
Klaatu (picked up their album Hope, it's kind of Beatles esq but very good)
Jethro Tull
Kyuss
Robin Trower (specifically the Bridge of Sighs album)
there's way more but I don't want to get into the more obvious stuff (like The Beatles or Rush)
