After Quicksilver Messenger Service, Ockerman played with a number of California-based acts, including IAM,[2] Snail, Airtight, The Ducks,[3] Bill Champlin, Rita Coolidge, Steve Marriott,[4] Tom Johnston,[5] Michael McDonald and Coco Montoya.
He also recorded with many of these performers, as well as working as a session musician with Bill Champlin and Jim Keltner, including a re-recording of "Nature Boy", the 1940s number one hit for Nat King Cole, with song author, Eden Ahbez.
The two concerts, at the Rio Theatre in Santa Cruz, and Don Quixote's International Music Hall in Felton, were recorded in anticipation of later 2009 release.
The school features a Hammond B3 organ and Leslie, once played by Booker T. Jones and Jimmy Smith, as well as a vintage Wurlitzer piano, Clavinet, and numerous guitars basses and percussion instruments.
[8] GuitArmy features professional musicians Tiran Porter on bass and David Tucker, former (Maria Muldaur,([Tommy Castro]) drummer and Musicscool teacher) on drums.
Lead vocalist James Durbin, then 19, also guested with the White Album Ensemble's "Across the Universe" concert in December 2008 and received a standing ovation for his vocal on "While My Guitar Gently Weeps".
After some touring, Durbin called Ockerman from Turkey, with an idea to put GuitArmy back together, and perform a Doors / Led Zeppelin concert, which sold out (the band was all Musicscool Alumni).
