Eleventh Hour was a hardcore band from Texas, and was around from 1993 to 1997. Here's the 1994 vinyl re-release of their 1993 demo. Good straight-forward hardcore with some slower and more metallic parts and pissed off vocals. Lyrically it deals with issues such as vivisection and the destruction of the rain-forest, and besides the lyrics in the booklet there's also an explanation of the lyrics for each song, which is always a cool thing. Besides this demo/7" the band also appeared on a couple of compilations. Check out their myspace for more information.
