The Moody Blues

They've sold millions and millions of albums and have been gigging since 1964—it's fair to say the Moody Blues have seen it all. The English band's shtick, meanwhile, is classic psych-pop and folk-tinged prog rock. Sure, they haven't released a new lick since 2003, but with an act like this, it's all about the golden oldies: "Tuesday Afternoon" and "Nights in White Satin" among many others. Dig out your bell-bottoms and get down.
