First conceived in 2004, Los Angeles, California's Intronaut started out as a friendly but loose side project concocted between Anubis Rising vocalist/guitarist Sacha Dunable and then Uphill Battle drummer Danny Walker (also ex-Exhumed. When their songwriting started to bear impressive fruit -- based upon the aggressive and progressive new sound made popular by Mastodon and, to a lesser degree, their own groups -- the duo called in fellow Exhumed guitarist/vocalist Leon del Muerte and ba**ist Joe Lester to help them cut the Null EP, released in early 2006 by Goodfellow Records. Barely six months later, Intronaut returned with that EP's logically named follow up, Void. ~ Eduardo Rivadavia, All Music Guide
