Their self-titled debut album was released in 1998 on Striving For Togetherness Records. In 1999 their second album, 'Should My Fist Eye', was released, this time on Cho'Sin Records. The final track on this album, 'Cinder', was recorded & performed by Drillpress, a band that drummer Larry Hundertmark was in before joining Neck, and they had never managed to release these recordings before. The full discography of Neck includes a 1996 demo, a 7" released in 1997 on Bittersweet Records, a self-released EP called 'Crawl Away' from 1999 and another album called 'Smart Bomb And The Swarm', which was self-released on their own label Lifeless Records in 2005. All of these seem pretty hard to find, so I don't have any of those unfortunately, sorry, but if anybody's willing to part with their copies, hit me up! They also appeared on a bunch of compilations, including the 'Fear No Evil' compilation, on Last Word Records, with among others my own band, Disdain, the 'Over The Edge vol. 3' compilation which I posted here and the 'Disintegrated - A Cure Tribute' compilation on Too Damn Hype. Neck's drummer now goes by the name Razor Tongue as the singer of Nassau Chainsaw, while other members went on to bands such as Car Bomb and Paiste Junkies.
Update: as Mark commented on this post, he has some Neck merch pics. Personally I hadn't seen any Neck merch (possibly because I live in Europe, hah), so my interest was piqued. And for those who are also interested:
