Worship & Tribute is Glassjaw's worst album by far. However "Must've Run All Day" is one of my favorite GJ tracks. Deffiniatly get Everything You Ever Needed To Know About Silence ...That thing is a classic. Their EP's and demo's are insanely hard to track down, but are relatively easy to download ...so I suggest you go that route. I would suggest you also try to find an mp3 of their live only track St.Alex, that thing is so beautiful.
Lastly despite what you may have heard, they haven't broken up and should have a new album out soon.
If you like GJ, check out Finch's What It Is To Burn album. Darryl even makes an apperance on it.
