1991's Gish is the debut album by alt-rock pioneers the Smashing Pumpkins. Produced by Butch Vig, Gish not only put the band and their guitar-centric, layered sound on the map, but it also served as one of the earliest releases of what would be deemed the alt-rock movement. Epic cuts like "I Am One," "Siva" and  "Rhinoceros" flash a unique and promising potential that would become fully realized two years later with their breakout genre-defining album Siamese Dream.
