Like if the KLF made “Chill Out” after a long, long New Orleans weekend, Weeks Island is an album of ambient pedal steel that is deep and rewarding. The solo project of Jonny Campos, guitarist of the Grammy-winning Cajun band Lost Bayou Ramblers, Weeks Island came to James Murphy and DFA Records via LCD Soundsystem’s Korey Richey and is now presented in remastered, expanded form.
