Remember when bands used to release more than one album per year? It wasn’t always so uncommon. These 10 acts were able to unleash two legitimate masterworks in the same calendar year.

Most of this is going to take you back to the ‘60s and ‘70s. Back in the early days of rock, bands typically spent much more time in the studio cranking out new works. Legends like Black Sabbath and Led Zeppelin started off their careers with a sonic barrage of groundbreaking music, as both acts released their debut and sophomore albums in the same calendar year. KISS did the same, though the brilliance of the face painted pioneers wasn’t widely acknowledged at first.

Bands like The Beatles and Deep Purple hit with a duo of classics well after they had become international phenoms. Imagine the experience of being a music fan in 1967 and being gifted with the Beatles' Sgt. Pepper’s Lonely Hearts Club Band and Magical Mystery Tour with just a few months separating the two.

A few modern acts have taken the route of multiple releases in one year, including System of a Down with Mezmerize and Hypnotize.
