Context_1 : 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.

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.
