Reclusive Santa Cruz Old Growth giants MAMMATUS return with Expanding Majesty, a masterwork of heavy music 8 years in the making.

A 69 minute magnum opus of kaleidoscopic guitars, soaring analog synths, wall-of-amps fuzz bass and 100ft drums. 4 side-long pieces of cosmic flight and sub-surface thunder take the listener deep into the band's unique vision of this world and beyond.

Mammatus has been conjuring up a heavy blend of riff laden, space trippin, proggy, hazy far out rock and roll for fifteen years now. Since forming in the shadows of the Santa Cruz Mountains of California in 2005, they've delighted the ears and minds of adventurous listeners around the world.
