I'm an unapologetic lover of compilations! They turn you on to new stuff, often include more dynamic and interesting transitions/juxtapositions than a same-y one band record, and are great for when you’re djing and have to pee.
Like many have said already, KBD, Bloodstains, Mississippi records tapes&comps, Back from The Grave, Girls in The Garage, Punk 45 etc. are absolute gems and have greatly expanded my knowledge and taste.
I’d also like to put in a good word for:
-N.O. Experience. Excellent punky power pop stuff out of Louisiana.
-Garage Punk Unknowns (speaks for itself)
-Messthetics DIY Compilations (they use the term “indie” but it’s safe, I promise)
AND I mustn't forget to include the 4 disc cd compilation that changed my life as a teenager when I checked it out from my local library. No Thanks: The 70’s Punk Rebellion.
Can't wait to check out the other recommendations on here. Comps rule.
