RTSR is the definitive unofficial online resource for information about the band Underworld. It consists of a huge collection of information (rtsr-underworld), an e-mail mailing list for bootleg trading (rtsr-trade), an Underworld web ring (rtsr-homeless trees) and a weekly internet radio show (rtsr-live).
RTSR began life as "Ride the Sainted Rhythms", a small Underworld fan site from the days before Underworld themselves had an official site.
In early 2003 rtsr-underworld merged with dirty.org (which in 2007 was renamed/moved to darktrain.org).
