On the music and image side, check out Iggy Pop and The Stooges, and of course The Ramones, for where punk started. Ramones are a bit odd here, because they wanted to recreate the energy of 50s-60s rock'n'roll, and as a result nobody else sounds quite like them, except bands that emulate them deliberately — but their songs work splendidly in the rock'n'roll style (can't find proper rock'n'roll covers, because they have a couple songs with that word in the title).

For where punk ended up, see Napalm Death — they married hardcore-punk to death metal, adding blast beats and inventing grindcore.
