Kenneth E. Gaspar (born 1953 in Waimānalo, Hawaii), more commonly known as Boom Gaspar, is an American musician who has performed with the American rock band Pearl Jam as a piano/keyboard/organ player since 2002.
Boom Gaspar grew up in Waimānalo, Hawaii. He started playing music when he was eleven years old. After graduating from Kailua High School, Gaspar spent the next thirty years doing local shows throughout Hawaii with acts such as the Mackey Feary Band, Harmony, Simplisity, and blues guitarist Albert Collins.
Pearl Jam vocalist Eddie Vedder first met Gaspar while in Hawaii. Gaspar was introduced to Vedder through C. J. Ramone. Gaspar has appeared on the Pearl Jam albums Riot Act (2002) and Pearl Jam (2006). He has a songwriting credit for the song "Love Boat Captain" which is on Riot Act. According to Gaspar, the song initially developed out of a jam session he had with Vedder shortly after the two first met. When they were done, Vedder asked Gaspar if he was "ready to go to Seattle." He has become known for his long solos during "Crazy Mary", a song originally written by Victoria Williams, which has become a fan favorite during live Pearl Jam shows. This often culminates in a guitar/organ duel between Gaspar and guitarist Mike McCready.
