Bob Weir will use his TRI studios with increased regularity in 2012. As previously reported, the guitarist will regroup Kenny Brooks, Jeff Chimenti, Mark Karan, Steve Kimock, Jay Lane, Robin Sylvester and Rob Wasserman for a free RatDog webcast on January 25. In all likelihood, he’ll also continue to post solo performances from time to time. To kick off 2012, Weir has released a solo take on “Corrina” he recently filmed at TRI.
