According to a recent post on Fuzz.com Maynard will be joining Tom Morello on his upcomingNightwatchmen tour:
Rage Against the Machine guitarist Tom Morello’s alter ego, The Nightwatchman, will kick off a two week tour starting April 15th with special guests in each city, including: Slash, Ben Harper, Perry Farrell, Maynard James Keenan of Tool and Puscifer, Boots Riley of The Coup and more to be announced.
Not exactly sure what the tourdates are, but I’d expect the gig featuring Maynard to be at the Los Angeles date.
The Melvins have announced their new album Nude With Boots which will be released on the 8th of July. The album will feature the same line-up as (A) Senile Animal (ie. with Big Business), and the release should be followed by a tour. Come to Australia this time please!
