Glass Harp is an American rock band that was formed in 1968 in Youngstown, Ohio. The band's original lineup consisted of Phil Keaggy on guitar and vocals, John Sferra on drums, and Dan Pecchio on bass. They were known for their virtuosic musicianship, experimental sound, and dynamic live performances.

The band's name was inspired by the glass harmonica, an instrument invented by Benjamin Franklin. The glass harmonica produces sound by rubbing wet fingers on the edges of glass bowls or tubes, and Glass Harp incorporated this ethereal sound into their music.

Glass Harp released their self-titled debut album in 1970, which featured a mix of psychedelic rock and blues-influenced tracks. They followed this up with two more albums, "Synergy" and "It Makes Me Glad," before disbanding in 1972.

Despite their relatively short career, Glass Harp has had a lasting influence on the rock music scene. Phil Keaggy went on to become a highly respected solo artist, and his guitar playing has been praised by the likes of Eric Clapton and Carlos Santana. The band has also been cited as an influence by other musicians, including The Smashing Pumpkins' Billy Corgan and Dream Theater's John Petrucci.

Glass Harp reunited for a series of concerts in 1997, and they continue to perform occasional shows to this day. Their music remains highly regarded by fans of progressive rock, and their legacy as one of the most innovative and talented bands of the 1970s is secure.
