varied, including bluegrass, rock, folk, blues, country, jazz, electronic music, gospel, funk, and reggae. Artists who sought Garcia's help included the likes of Jefferson Airplane (most notably Surrealistic Pillow, Garcia being listed as their "spiritual advisor"). Garcia himself recalled in a mid-1967 interview that he'd played the high lead on "Today," played on "Plastic Fantastic Lover" and "Comin' Back to Me" on that album. Others include Tom Fogerty, David Bromberg, Robert Hunter (Liberty, on Relix Records), Paul Pena, Peter Rowan, Warren Zevon, Country Joe McDonald, Pete Sears, Ken Nordine, Ornette Coleman, Bruce Hornsby, Bob Dylan, It's a Beautiful Day, and many more. In 1995 Garcia played on three tracks for the CD Blue Incantation by guitarist Sanjay Mishra, making it his last studio collaboration. Throughout the early 1970s, Garcia, Lesh, Grateful Dead drummer Mickey Hart, and David Crosby collaborated intermittently with MIT-educated composer and biologist Ned Lagin on several projects in the realm of early ambient music; these include the album Seastones (released by the Ned Lagin on the Round Records subsidiary) and L, an unfinished dance work composed by Ned Lagin. In 1970, Garcia participated in the soundtrack for the film Zabriskie Point. Garcia also played pedal steel guitar for fellow-San Francisco musicians New Riders of the Purple Sage from their initial dates in 1969 to October 1971, when increased commitments with the Dead forced him to opt out of the group. He appears as a band member on their debut album New Riders of the Purple Sage, and produced Home, Home on the Road, a 1974 live album by the band. He also contributed pedal steel guitar to the enduring hit "Teach Your Children" by Crosby, Stills, Nash, & Young. Garcia also played steel guitar licks on Brewer & Shipley's 1970 album Tarkio. Despite considering himself a novice on the pedal steel, Garcia routinely ranked high in player polls. After a long lapse from playing the pedal steel, he played it once more during several of the Dead's concerts with Bob Dylan in the summer of 1987. In 1988, Garcia agreed to perform at several major benefits including the "Soviet American Peace Walk" concert at the Band Shell, in Golden Gate Park, San Francisco, that drew 25,000 people. He was asked to play by longtime friend and fellow musician, Pete Sears, who played piano with all the bands that day, and also procured all the other musicians. Garcia,
