Also, the best music was made in that time period.
Why do you have groups like "The Bee-Gees" in OP... They are disco lol.
Jimi Hendrix: IzabellaAlso, Im not a big fan of Chicago, but the stuff Ive heard from them is nice. I know they were around from 1970 through the 80s, and are still touring today, but like I said, I do not know which album is the best. In the 70s they mixed a brass section with guitars and stuff, which was cool. They got a bit more "rock" like later on, and the 80s really influenced their sound, I think.
Chicago: Chicago II (Full Album)
