If nothing else, Slave Ambient is deeply personal. Dropping tomorrow via Secretly Canadian, the War on Drugs‘ second proper full-length was, for outfit mastermind Adam Granduciel, a chance to prove his worth, talent and musical acumen as one of the most prolific and experimental artists to come out of Philadelphia. It’s a record of layered complexity, of intense brevity, of changing hearts, and even in it stark, woven landscape, this record, four years in the making, is voluminously grand. The War on Drugs will be celebrating the release of their highly-anticipated album this Thursday at Johnny Brenda’s with Caveman and Tin Horses. We had a chance to chat with Granduciel about his unconventional approach to creating Slave Ambient, his upcoming tour in support of the album, and why cassettes blow mp3s out of the water HERE.
