I was turned onto Quicksand pretty late in the game, but these guys fit into a similar 90's niche as Helmet even if they aren't as well known. In any case, their two albums Slip and Manic Compression were masterpieces that I listen to as often as possible. Excitingly, the band just released their first single in a LONG time; and they seem to pick up right around where they left off. Jump into a time capsile and listen to "Illuminant" below. Watch for an album later this year.
