Siddhartha is a five LP box set by Billy Corgan documenting his eight-hour ambient musical interpretation of Hermann Hesse's Siddhartha on February 28, 2014 at Madame ZuZu's. The performance was an improvisation using a Roland System-100M 182 analog modular synthesizer, with some guitar contributions from Jeff Schroeder. The recording was sold exclusively through Madame ZuZu's website at $375 each. Only 500 hand-numbered copies were made, the first 250 signed by Corgan. The set also came with a custom art print by Linda Strawberry, a personal Stylophone synthesizer, and a black WPC hat.
