The only Hammerhead I own is a 7" AmRep Research and Development Series
picture disc: Peep b/w V.U. So good.
Be sure to familiarize yourself with Craig Clouse's recent band TODD. I did a C/NC recently here
As totally esoteric as it is to say, this is their best release. These two songs, when they were all I had by them, made me think they were probably the best band in the world. Subsequent stuff of theirs (and I bought almost all of it) brought me back to earth.
Their full lengths are peppered with some really good stuff ("Double Negative", the title track from "Duh, the Big City") and a lot of so-so. Still, their good stuff was great and they get the Not Crap from YT.
Hazlemeyer's graphics, though - they are Crap.
