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.

Wild in the Streets is the second studio album by the hardcore punk band Circle Jerks.
 It was originally released on March 4, 1982 through Faulty Products, a sub-label of I.R.S. Records.
 In 1988, the album was remixed and reissued on Frontier Records.
 The title track is a cover song of the Garland Jeffreys song of the same name.
 Mike Ness of Social Distortion can be seen on the cover of the album; running wild in the streets.
Under the Influences, the second (and most recent) solo album from Social Distortion's Mike Ness, is a compilation of country, rock, and bluegrass covers released just six months after his first solo effort, "Cheating at Solitaire".
 As the title implies, Ness intends the album to be an illustration of the music that shaped him.
 Songs as diverse as "I Fought the Law" and "Wildwood Flower" make their appearance, each with Mike Ness's unique spin.
 Included is a honky tonk version of Social Distortion staple, "Ball and Chain".
Social Distortion is an American punk rock band which currently consists of vocalist and guitarist Mike Ness, guitarist Jonny "2 Bags" Wickersham, bassist Brent Harding and drummer David Hidalgo Jr..
 The band was formed in Fullerton, California in 1978, and originally comprised Ness, Rikk Agnew and his brother Frank on guitar, Casey Royer on drums, Tom Corvin on vocals and Mark Garrett on bass.
 The first lineup change took place in 1979, when Garrett was replaced by Dennis Danell, who had known Ness for years.
Cheating at Solitaire is the first solo album from Social Distortion frontman Mike Ness.
 Released in 1999, it bypasses much of Social Distortion's punk muscle in favor of a more roots-oriented approach to rock and roll.
 It features cameos by Bruce Springsteen, Brian Setzer, and members of Royal Crown Revue.
 Johnny Cash was invited to perform on the song "Ballad of a Lonely Man", but was too ill to record at the time.
The Social Distortion South American Tour was a concert tour by Social Distortion.
 It was first announced on December 29, 2009.

 Some of the dates on the tour are rescheduled shows from fall 2012 that were cancelled due to Hurricane Sandy.
 The band will also make appearances at the annual Hootenanny at Oak Valley Ranch in California, their first as Social Distortion since 2007.
 Mike Ness made an appearance at the 2008 festival, but he was touring with his solo band.
 The band will also appear at the Free Press Summer Fest in Houston, Texas, and at this year's North by Northeast in Toronto.
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.
