Earthshaker is the third studio album by American heavy metal band Y&T, released in 1981.[3] It is their first album under the name Y&T, after shortening it from Yesterday and Today, and their first album with A&M Records. A mix of hard rock and heavy metal songs, AllMusic's Eduardo Rivadavia named this album as the best release in the band's career, the album most faithfully representing "the power and energy" of Y&T's "legendary concerts".[2]
The album was re-released in 2006. Contrary to popular belief, the Japanese heavy metal band Earthshaker did not take their name from this album, rather they took it from the song "Earthshaker" off of Y&T's first album Yesterday and Today.
