Mass Conception is an alternative rock band from Burlington, Ontario, Canada.

With diverse influences from Joy Division and U2 to Johnny Cash and Janis Joplin, Mass Conception meshes alternative rock and whiskey-bar vocals to create a multi-layered, enveloping sound rich with melodic hooks.

With their latest release, Greatest Show Never Seen, Mass Conception has reshaped their signature sound. This ambitious effort captures the paradoxes of Mass Conception: it is complex but accessible, intelligent but raw, straightforward but hard to pin down.

Greatest Show Never Seen is the follow up to their 2008 debut EP, No Pun Intended, in which Mass Conception teamed with world-renowned producer Bob Lanois.
