Billy Bultheel and Alexander Iezzi team up as 33 for an equal-parts brutal and beautiful array of banging hardcore rave, inward-looking chamber music, and artful punk. The fact that composer and performance-maker Bultheel and artist Iezzi come from very different artistic backgrounds contributes to the creative freedom that their collaborative output radiates. Stomping techno fills, blistering samples, and sudden bolts of noise punctuate funereal choral chants, mournful string sections, and melancholic piano notes. Picture a woeful opera house that has been taken over for an experimental club night, or a royal concert hall made from slabs of concrete and you’re nearly there. For this live show Bultheel and Iezzi are performing alongside cellist Patrick Belaga and the vocalists Ivan Cheng and Steve Katona.
