UG is an abbreviation for the guitar tablature website "Ultimate-Guitar.com". The website, as well as containing music news, guitar video lessons, equipment and album reviews, contains a forum where users can discuss whatever they wish, subforums include "Riffs and Recordings", "Modern Rock", "Classic Rock" and an "Off topic discussion area", entitled "The Pit". Users from the site entered a competition to have their music put together on an album, and the winners were amalgamated and collected into one 19 track download only album, entitled "What's Next?(UG Original Album)". Subsequently, a three part album, entitled "Pitropolis" (45 songs) and a Christmas album ("The UG Christmas Album") have also been released in a similar manner. The artists were not paid and it all happened through the web site due to the users' love of music. Read more on Last.fm.
