Alternative rock icons The Smashing Pumpkins are recognized for their amalgam of progressive rock, heavy metal, goth, psychedelia, and dream pop; a layered, powerful style driven by swirling, distorted guitars that churned beneath lead singer/songwriter Billy Corgan's angst-ridden lyrics. One of the most visible bands of '90s, alongside grunge acts like Nirvana and Pearl Jam, the Smashing Pumpkins achieved mainstream success over the decade with classic releases "Siamese Dream" and "Mellon Collie" and the "Infinite Sadness".
