High Quality Content by WIKIPEDIA articles! Since I Left You is the debut studio album by Australian electronic dance music group The Avalanches, which was released on 27 November 2000. Produced by The Avalanches` members Robbie Chater and Darren Seltmann (under the pseudonym Bobbydazzler), it was issued on Modular Recordings. The album was created in two separate near-identical studios by Chater and Seltmann, passing audio mixes of records they sampled. The album contains about 3500 vinyl samples of various genres of music. As it was not originally intended for international release, the duo did not worry about copyright restrictions nor attempt to keep track of which samples they would need to clear.
