I stumble across this article this morning on SignOnSanDiego.com, talking about Humphrey’s Concerts by the Bay venue in San Diego, which mentions that:
artists include Jackson Browne, LeAnn Rimes, Loggins & Messina, Carlos Mencia and Puscifer (Tool singer Maynard James Keenan), who will all be making their debuts at the intimate Shelter Island venue this year.
No further info in the article that I could see, which focuses on the venues success, and it’s policy of trying to keep concert ticket prices cheap.
