Nailbomb was a heavy metal band formed in 1994 as a side project by Brazilian musician Max Cavalera of Sepultura, Cavalera Conspiracy and Soulfly, and British musician Alex Newport of Fudge Tunnel. They played a combination of primarily industrial metal and thrash metal. The band recorded one studio album, Point Blank, and played a warmup live performance and their last ever performance at the 1995 Dynamo Open Air Festival two days later, after which the band disbanded.
