Smashing Pumpkins rocker Billy Corgan has announced plans to perform a marathon eight-hour free gig at his Chicago, Illinois tea shop.

The music for the Madame ZuZu's Teahouse show will be inspired by Hermann Hesse's novel Siddhartha, and will take place on 28 February (14).

Announcing the show on, Corgan says his performance will be "centered around an ambient/musical interpretation of Hermann Hesse's Siddhartha; built by modular synthesis, on the fly."

He adds, "Readings of the text to go hand in hand with whatever is created."

Corgan is currently working on the ninth Smashing Pumpkins studio album.
