No one should be all that surprised that the endlessly prolific Billy Corgan just announced an eight-hour concert, but the content of that performance might catch you off guard. As Spin points out, in a Facebook post today, the Smashing Pumpkins leader announced he’ll be performing an ambient, instrumental interpretation of Hermann Hesse’s existential novel Siddhartha at his Chicago tea shop, Madame ZuZu’s Teahouse. Corgan expects the free performance to last between eight and nine hours. Read the full post below:

On 2//28 I’ll be doing a show at Madame ZuZu’s Teahouse; start time noon, and due to nature of performance it’ll last 8-9 hours. So see http://MadameZuzus.com in coming days for details on seating and admissions. As with all our events there is no charge. Performance will be centered around an ambient/musical interpretation of Hermann Hesse’s Siddhartha; built by modular synthesis, on the fly. Readings of the text to go hand in hand with whatever is created; + the first @Hexistential poster, and event t-shirts too. Hope to see you there.

This means you have 10 days to read Siddharta, or at least to brush up on the Sparknotes. Corgan’s recently revived Facebook page also reports that he’s working on new Smashing Pumpkins songs, which, in light of 2012’s return to form Oceania, is good news.
