HoBoLeMa was an improvisational instrumental supergroup which consisted of Allan Holdsworth, Terry Bozzio, Tony Levin and Pat Mastelotto. The group toured Japan in November 2008, the West Coast of the United States in January 2010 and Europe in April and May 2010. The name "HoBoLeMa" comes from combining the first two letters of each of their last names. In January 2009, GuitarPlayer Magazine interviewed all four members of the group about the process of improvisation, and recorded three excerpts from a show in Oakland, California, and posted them online.
