It is an amazing instrumental album. Elements from funk, metal, rock, progressive, shred, dub, techno, shred are all mixed in 9 incredible songs. In fact there's enough genres covered on here to satisfy almost anyone. The supergroup is made up of Bootsy Collins (Funkadelic), Buckethead, Brain (Primus) and Bernie Worrell (Funkadelic) This is one of my all time favorite albums, simply awesome. I highly recommend it to anyone
