IPECAC dont play that 
Not true. "This Machine Kills Artists" was released on 10" vinyl via AmRep first, then standard 12" release through Ipecac, and wasn't PAT the same deal? I doubt Ipecac says Melvins can't touch that album and have AmRep reissue a totally different version.
I just dusted off the H.A.T. 45s the other week, and they've been in rotation. I too would love to see a standard 12" double gatefold deluxe version of H.A.T. Probably could do the album in order as sides 1-2-3, and throw the covers on side 4. If anything had to be chopped off, make it the Foaming fast version. Not sure what they were thinking with that. Interesting, but the least essential b-side of the bunch.
