White Light, White Heat, White Trash: White Light, White Heat, White Trash is the fifth album by American punk rock band, Social Distortion, released on September 17, 1996, by Epic Records.  The album was produced by Michael Beinhorn.  "White Light, White Heat, White Trash" is the last Social Distortion studio album to feature guitarist Dennis Danell who died on February 29, 2000, of a cerebral aneurysm at the age of 38.  He did however appear on live album "Live at the Roxy" in 1998.  It is also the band's last release on Epic Records.  The album received Social Distortion's highest chart position at the time, entering the "Billboard" 200 album chart at #27.  In the first week of its release, "White Light, White Heat, White Trash" sold 30,000 copies.  Stylistically, the album is harder and considered a return to their punk roots.

Social Distortion: Social Distortion is an American punk rock band formed in 1978 in Fullerton, California.  The band currently consists of Mike Ness (lead vocals, lead guitar), Jonny Wickersham (rhythm guitar, backing vocals), Brent Harding (bass, backing vocals), David Hidalgo Jr. (drums), and David Kalish (keyboards).

Social Distortion South American Tour: The Social Distortion South American Tour was a concert tour by Social Distortion.  It was first announced on December 29, 2009.  It would become Social Distortion's first time in South America in their entire career.  Frontman Mike Ness had this to say:

Social Distortion Winter 2012 Tour: The Winter Tour (also known as "House of Blues Residency" was a tour by Social Distortion.  As its name applies, most of the shows were based out of the House of Blues in Orange County (Anaheim, San Diego, West Hollywood) with a couple of shows heading out to Las Vegas and Tempe, Arizona.  Even though similar, this tour was not a part of the Hard Times and Nursery Rhymes tour, as most of the material played here was pulled from most of the band's catalog.  This is also not the first time Social Distortion has done a tour like this, it has been done before numerous times since 2001.  As with previous House of Blues tours, the band played rare songs and new songs and brought out guests this time, such as Billy Gibbons and Mike Ness' own son Julian Ness.  They also brought out Eric "Jailhouse Blues" Von Herzen who played harp for "It Coulda Been Me" and "Drug Train" on Social Distortion (album) and they also played ZZ Top's La Grange (song) with Billy Gibbons.  The band also premiered songs like "Far Side of Nowhere", "Writing On the Wall" and performed songs that have not been played in a while like "It Coulda Been Me", "99 to Life", "Footprints On My Ceiling", "Hour of Darkness", "Diamond In the Rough" and even played the White Light, White Heat, White Trash album in its entirety at some shows.

Sex, Love and Rock 'n' Roll: Sex, Love and Rock 'n' Roll is the sixth album by American punk rock band Social Distortion.  It is their first studio album in eight years, since the release of "White Light, White Heat, White Trash" in 1996, the longest gap between Social Distortion's studio albums to date.  The album was originally scheduled to be released in the fall of 2000, but was not yet completed, and it was officially released on September 28, 2004.  A great deal of the album is a musical eulogy to former guitarist Dennis Danell, who died in 2000.  The album's opening track, "Reach for the Sky", was released in late 2004 and became one of Social Distortion's biggest hits.

Mission of Burma: Mission of Burma is an American post-punk band formed in Boston, Massachusetts in 1979.  The band was formed by Roger Miller (guitar), Clint Conley (bass), Peter Prescott (drums) and Martin Swope (tape manipulator/sound engineer).  Miller, Conley and Prescott share singing and songwriting duties.

Social Distortion 2001 Tour: The Social Distortion 2001 Tour was a concert tour by Social Distortion.  It was their first tour in three years as Mike Ness was busy with his solo project, touring throughout 1999 and the rest of the band was off doing their own thing.  Dennis Danell was working as a producer in the Orange County area for up-and-coming punk bands and he was also in the process of recording demos for his side project.  John Maurer had started his own side band as well, Foxy.  Foxy had just released its debut album.  On this tour, the band premiered new songs off of the Sex, Love and Rock 'n' Roll album like, "Footprints On My Ceiling", "I Wasn't Born to Follow" and "Angel's Wings" and "Road Zombie", although, "Angel's Wings" sounded almost different with different lyrics than its studio counterpart.  They even played a couple songs that were rare to hear at a Social Distortion concert those days, "Hour of Darkness", "Backstreet Girl", "I Won't Run No More", "When She Begins", "King of Fools" and "Down On the World Again".  This was also one of the few tours where Social Distortion did not have ANY opening acts.

Hard Times and Nursery Rhymes: Hard Times and Nursery Rhymes is the seventh studio album by the American punk rock band Social Distortion, released on January 18, 2011.  It is the band's first album recorded with bassist Brent Harding, their first album of new material since 2004's "Sex, Love and Rock 'n' Roll", and their first release on Epitaph Records.  Work on the album began in 2006 and it was originally forecast for a 2007 release, but was pushed back several times while the band continued touring and writing new material.  After four years of writing, Social Distortion recorded the album from February to July 2010 at Ocean Studios in Burbank, California.  Drummer Atom Willard left the group during the recording sessions in favor of his other band, Angels & Airwaves.  He was temporarily replaced by Scott Reeder before David Hidalgo, Jr. joined as the band's new permanent drummer.  Despite being listed as a band member on the album, Hidalgo did not actually play on it; instead, the band hired session musician Josh Freese to record the drum tracks.
