For New Music Friday, we have something a little less than new.

In 1976, the Canadian rock band Rush released the Rushiest of Rush albums, 2112. Despite pleas from their record label to write short pop songs, Rush put together a twenty minute, seven-part suite telling the story of a future world under the thumb of the “Priests of the Temples of Syrinx” that might be given freedom when a man discovers an ancient guitar.

It’s silly and over-composed and just about perfect.

This week, for its 40th anniversary, a new edition of the classic album was released featuring rare live tracks and previously unreleased material along with newly-recorded cover tracks tracks by Dave Grohl and Taylor Hawkins of Foo Fighters, Nick Raskulinecz, Billy Talent, Steven Wilson, Jacob Moon, and Alice In Chains.

The 40th anniversary edition of 2112 is available to stream on your computer or mobile device at hoopladigital.com.
