Glassjaw is an American post-hardcore band from Long Island, New York. The band is fronted by vocalist Daryl Palumbo and guitarist Justin Beck. The band has been influential in the progression of the underground music scene in the eastern United States and United Kingdom and on the post-hardcore genre, and are known for their intense live shows and previously frequent line-up changes.
The band formed in the summer of 1993 after Palumbo and Beck met each other at camp. Of the band name, Beck has said: “We had a list of names, and we were just like, let’s pick one of these band names which ones the coolest. At the time there were a bunch of bands coming out with two names in one like that, like mouthpiece, curbjaw, stuff like that. We were going down the list, and the first name that I liked was Swiftkick. I’m all like, that’s a sick name. But for some reason Glassjaw stuck. There’s really no reason behind it; it just sounded cool.”
The band played their first show in 1994 in Oceanside, NY. In the early days, Beck and Weinstock were also playing with Jewish straight edge metalcore band, Sons of Abraham. Sons of Abraham constitute an important influence on Glassjaw, songs such as Hurting and Shoving (She Should Have Let Me Sleep) by Glassjaw drawing particularly on earlier Sons of Abraham releases. Palumbo was in his own straight-edge band called XbustedX. The group’s line-up changed constantly in their early years while they played in the local New York hardcore scene. Beck’s primary instrument throughout this time was drums, but switched to bass guitar when Ariel Telford left the band in 1998, and then switched to lead guitar when Kris Baldwin left and Manuel Carrero joined the band in 1999. From 1994-1999 the band did several demo recordings of some songs that would eventually appear on their official releases, as well as several other compositions that would not see official release.
