This is exactly what a demo tape should be—five rough and ragged songs from a band that is already good but still finding their footing. This is simply excellent hardcore punk with a phenomenal guitar tone. My biggest complaint with most current hardcore is that the guitars sound like shit but Sin Cave has near-perfect tone. The recording is lo-fi but everything can be heard quite well. The rhythm section is solid with simple and great-sounding bass lines and drums that are right for the song without a lot of showing off. There’s lots of reverb in the vocals, one song has lyrics entirely in Spanish, and it’s all packaged in a very cool-looking glittery cassette with a lyric sheet. Denver hardcore roolz, okay? –Mike Frame (Self-released, sincave.bandcamp.com)
