Siege plays with crazy speed on their Drop Dead album. It runs about 15 or 16 minutes takes aspects of early hardcore like acts like black flag and suicidal tendencies and makes something faster. The music never sounds tired, awkward, or boring.
There isnt much else to say. Its a good album to add to your collection of those bands who liked to play extreme punk. In the realm of punk, this is only surpassed by 'Extreme Noise Terror' 5 years later on their "Holocaust In Your Head" album.
