Isis - Sawblade CD (Hydra Head, 1999)
200 CDr's were released attached to a full-sized metallic saw blade, only sold during their 1999 tour with Neurosis and Candiria. The Isis logo was painted on to the face of the saw blade, the CDr was contained within folded paper liner-notes and bolted onto the back of the blade. All were hand-numbered. 160 were with black saw blades.
