Glassjaw fansite Glassjaw.net posted a statement from guitarist Todd Weinstock:

Over a year ago in August, Glassjaw played our last show after years of touring and we decided to take a hiatus. We were all fried and needed time to do our own things. It got to the point where we were on top of each other way too much and it was starting to take its toll. Everyone decided to take some time off and do what they wanted to do for awhile. Fast Forward to a few weeks ago; people start asking me about this Glassjaw show in December that I know nothing about. So I look on the computer and find that there is a confirmed show.

After thinking this was a mistake I called [Justin] Beck and just wanted to clarify. I found out Beck's vision of Glassjaw these days is vastly different than mine. As far as I know, Beck plans to play the show with only himself on guitar, Daryl, and two hired musicians on drums on bass. After seeing Beck's vision of Glassjaw I realized I was not part of it anymore.

I didn't quit the band, I'm just not in it anymore. I'm not really sure what the future of Glassjaw will be, if any. For almost 10 years of my life I've had some of the most amazing times with Glassjaw. I've met great people, bands, friends, and made great music that will always be a part of me. I didn't expect it to end like this but I have to move on.

The band's last release was 2002's Worship and Tribute, though vocalist Daryl Palumbo joined Dan The Automator to release Decadence, under the name Head Automatica
