The 13 tracks of shrieking, strangulated fuzz guitar and heavy riffing found on Pure Rock Fury are as vital as the title demands. Think Led Zeppelin II run through the monolithic speaker-stacks of desert-rock innovators Kyuss. That Pure Rock Fury is an instant heavy-music landmark is certainly due in part to special guests guitarist Scott Weinrich of stoner-rock heavy hitters Spirit Caravan and guitar mystics Sixty Watt Shaman. But when Clutch hit their stride, they clearly don´t need any help. Witness the snatches of live performance that culminate in the staggering, frenzied, and shrieking "Spacegrass." Pure Rock Fury elevates Clutch to the stoner-rock elite.
