Johnson’s professional career began after befriending G. Love while surfing. G. Love would later record Johnson’s song ‘Rodeo Clowns’ for his 1999 album Philadelphonic. Johnson sang and played on the track, and it became the first single from the album.
Johnson then co-directed Thicker Than Water, a documentary surf film released in 2000. He also composed the accompanying soundtrack.
Johnson’s four-track music demo soon caught the ear of Ben Harper’s producer, J. P. Plunier, who worked with Johnson on his debut album Brushfire Fairytales in early 2001 with Harper and his Weissenborn lap steel guitar making a guest appearance. Brushfire Fairytales was released on February 1, 2001.
Johnson went back into the studio with Adam Topol (drums, percussion) and Merlo Podlewski (bass), who played on Brushfire Fairytales, and Mario Caldato Jr on production duties, to record his second full-length album On and On. It was the first album to be recorded at Johnson’s Mango Tree Studio in Johnson’s home town of North Shore, Oahu, and the first to be released through The Moonshine Conspiracy Records. On and On was released on May 6, 2003. Johnson credits most of his inspiration for this album from childhood friend Andrew Brown.
In October 2004, Johnson returned to the Mango Tree Studio with Topol and Podlewski along with Zach Gill (of Animal Liberation Orchestra) playing accordion, melodica and piano, to record his follow-up to 2003’s On and On. In Between Dreams was released on March 1, 2005.
Sing-A-Longs and Lullabies for the Film Curious George is a soundtrack album by Johnson, released on February 7, 2006. The album also features Adam Topol, Ben Harper, G. Love, Kawika Kahiapo, Matt Costa, Merlo Podlewski and Zach Gill. It was the first soundtrack to make it to number 1 since the Bad Boys II soundtrack in August 2003 and was the first soundtrack for an animated film to top the Billboard 200 since the Pocahontas soundtrack in July 1995.
Johnson enlisted J.P. Plunier to produce his fourth full-length studio album, Sleep Through the Static. It was recorded using 100% solar energy at the Solar-Powered Plastic Plant studio in Los Angeles. The album featured Gill (keys), Podlewski (bass) and Topol (drums, percussion). Johnson produced Animal Liberation Orchestra’s fifth studio album, Man of the World, which was released February 9, 2010.
