Professor Satchafunkilus and the Musterion of Rock is the 12th studio album by guitarist Joe Satriani. The title has Greco-Biblical connotations. The initial part, Professor Satchafunkilus, is an extension of Satriani's nickname, Satch. The second part, in particular, the word "Musterion" is a Greek word meaning "Something which cannot be known until it is revealed" in English this is roughly equivalent to a secret (not "mystery" as it is commonly misinterpreted).
Satriani has recently embarked on a special "Guitar Center Sessions" tour, which began on the release date of the album lasted through to April 11. Following this, Satriani embarked on a worldwide tour, kicking off April 30 in Lisbon, Portugal, before moving to Australia, South America and will finally be returning to the U.S. in the fall of 2008.
