I respect & endorse your conditions - gotta have standards. I’m pretty old (55) and still love some of the old stuff (but love the new stuff more to be honest).
Trashmen would be great, followed up with the Cramps would be awesome – hopefully your client is a little bit adventurous. Mixing up the “eras” is always fun. I’d do some old Animals, Kinks & Stones with some good old Sex Pistols, Clash, Ramones & the Zeroes. And Devo’s “Satisfaction” is always good for a bridge to yesteryear. Here are some other bands whose stuff is still fun to hear – Standells, the Count Five, the Sonics, Nashville Teens, Moby Grape (just the rockin’ stuff), Syndicate of Sound, Yardbirds, Them, the Seeds, there’s more I’m sure but my old memory is fading fast . . .
