Watch Bombuj. Brazilian speed-thrash-death metal band Sepultura are legendary for the extreme degree to which they delve into the depths of their genre. Always striving to be louder, faster, and deadlier (metaphorically, of course), Sepultura have inspired a countless number of modern metal bands as well as legions of obsessive fans. Under Siege was filmed live at Zeleste in Barcelona, Spain. For nearly an hour, Sepultura thrash through ten of their songs.
