Overkill emerged from New Jersey in the early 1980s to become one of thrash metal's most vital forces. The Years Of Decay arrived in 1989 on Megaforce, capturing the band at a peak moment of controlled fury. Bobby Ellsworth's vocals cut through walls of dense, intricate riffing, while the rhythm section drives everything with mechanical precision. This is thrash metal as intellectual brutality, with songs like Time To Kill and Elimination building complex arrangements that never sacrifice raw power and aggression. The cassette format captures the full impact of these carefully constructed songs. Essential for anyone serious about thrash metal history.
