Neurosis' Scott Kelly performs with Mastodon at Scion Rock Fest; video available

Scott Kelly, one of three founding members of long-running Oakland, California-based industrial/alternative/metal pioneers Neurosis, performed "Crystal Skull", "Divinations", and "Aqua Dementia" with Mastodon at this past Saturday night's (February 28) Scion Rock Fest at The Masquerade in Atlanta, Georgia.

Low-quality fan-filmed video footage of the performance can be viewed below.

Neurosis will stage the European version of its "Beyond The Pale" event on Saturday, April 25 at the 013 venue in Tilburg, Holland as part of the Roadburn festival.

Neurosis' latest album, entitled "Given to the Rising", was released in June 2007.

Mastodon will embark on a spring U.S. headlining tour in support of its second album for Reprise Records, "Crack The Skye". Mastodon will perform "Crack The Skye" in its entirety along with career-spanning surprises and plenty of visual stimulus in store. This first tour behind the groundbreaking new album will sweep across the U.S. and Canada, playing to smaller theaters and clubs to insure a maximum and up-close intimate environment in which to be exposed to brand new songs and old favorites for Mastodon fans. Support on the trek will come from Kylesa and Intronaut.
