The Born Bad series did a pretty good job at cataloguing the Cramps direct influences (hooks that Ivy used, songs they covered, songs they combined). I’ve loved 60s punk and psychedelia for well, jeez, 25 years or so now directly because of the Cramps and the 80s neo-psychedelia (Plasticland, TellTale Hearts, etc).
Check out Ugly Things[/url] – currently one of the best mags on this kind of stuff (although I don’t share their love of late 70s power pop). And also check out the 60s Comp Database link. Nuggets was just a starting point. Over the years people unearthed many seriously unhinged bits of vinyl.
You might also like to checkout the late 80s/early 90s Liverpool psych band Walkingseeds, esp. their ‘Upwind of Disaster, Downwind of Atonement’ album for one the better latter stabs at postpunk garage/psych. ‘Louie, Louie, Louie’ is stunning 🙂
