Flesheaters – Disintegraton Nation (Upsetter) 1978. The first Flesheaters EP is pretty stratightforward early LA punk rock with the waaaaaaay over-the-top Chris D vocals above the mix. My understanding is that Chris recruited the local band The Flyboys to be his backup band on this one. It makes sense because it sounds very similar to the Flyboys 7inch.
Chris would go on to do the great No Questions Asked LP with another ad-hoc group containing Stan Ridgeway of Wall of Voodoo. After that comes the classic “A Minute To Pray, A Second To Die” with another group of Flesheaters. This is where it started though.
