Following his involvement in Beatnik Inc, Dolby returned to his musical career in 2006. He performed his first solo public show in 15 years at the Red Devil Lounge in San Francisco, California on 21 January 2006, surprising the crowd who were there to see local band Notorious. He then launched an American tour, the Sole Inhabitant Tour, on 12 April, comprising a string of small dates in California, a science education benefit in Boulder, Colorado, and gigs across America before receptive crowds.
