In 1990 Gwar released their second album, "Scumdogs of The Universe". They left Shimmy Disc Records and recorded for Metal Blade Records. Gwar's music changed from hardcore punk, in "Scumdogs of the Universe" they have more of a crossover thrash/punk rock sound. The band's first album, "Hell O!", did not have any famous songs, but Scumdogs includes Gwar's first two famous songs, "Sick of You" and "King Queen"
