With 1979’s Overkill, Motörhead established, once and for all, that they were the band that could marry the full-speed-ahead momentum of punk to the lay-waste-to-the-landscape power of metal. While the longest songs—“Overkill” and “Limb from Limb”—open and close the album, almost everything between makes its unpretty point in less than three minutes. Anthems like “Stay Clean” and the ZZ Top-indebted “No Class” kick the bosses where it counts, inspiring generations of thrash and oi! street urchins who never came close to topping this one.
