Walter Becker of Steely Dan plays bass guitar on and co-produced All One (2010), which also features Rick Allen of Def Leppard on drums and Steve Gorn on flute. He has also appeared on an album with Baird Hersey & Prana, a group combining Western music and overtone singing, entitled Gathering in the Light. Two of his albums have featured Hans Christian as a guest multi-instrumentalist, and Sting appears on the album Pilgrim Heart. Krishna Das has been associated with many other artists. He was referred to as the 'Rockstar of Yoga' by the Grammys when he was nominated for a 2013 Grammy Award. In August 1970 Krishna Das traveled to India, where, as Ram Dass had done, he became a devotee of the Hindu guru Neem Karoli Baba (Maharaj-ji). For a brief time, Jeff Kagel, then a student at State University of New York at Stony Brook, was the band's lead singer, but he quit. In June 1967, a small group of high school and college students on Long Island formed a rock band that would eventually become Blue Öyster Cult.
