The Avalanches 2000 album Since I Left You was a one-off work of near genius by a six piece from Australia, made up of over 3500 vinyl samples, and a total joy to listen to. The song that made the biggest impact over here was Frontier Psychiatrist but the rest of the double vinyl album was just as good.
Laid back vibes-check. Jazzy flute sample- check. Ghostly backing vocals- check. 60s style lead vocal sample- check. Sumptuous strings- check.
