Born in Cleveland, Ohio on October 11, 1955, Peter Sprague was raised in Colorado until 1963, when his family moved to Del Mar, California. Inspired by his father's love of jazz, he took up the guitar when he was twelve. By the age of fifteen he was devoting all his time and energy to learning music. He studied with San Diego jazz guitarist Bill Coleman, played in his high school stage band, and formed his first group, the Minor Jazz Quartet.
Following a year's study at the Interlochen Arts Academy, Sprague studied privately and performed around the San Diego area until 1976. That year found him moving to Boston to study with many notable musicians including Pat Metheny, Madame Chaloff and Albin Czak (a classical guitarist). Peter returned to San Diego in 1978 and formed a jazz group called The Dance Of The Universe Orchestra that featured Kevyn Lettau, John Leftwich, and Peter's brother, Tripp Sprague on saxophone.
Peter has recorded many of his own albums on the Concord, Xanadu, and SBE record labels and has been a guest artist on many other records. Chick Corea, Hubert Laws, David Benoit, and Sergio Mendes are only but a few of the many great artists Peter has worked with. His debut with the Chick Corea band was a series of concerts at Disneyland on Memorial Day weekend. In a review the following day in the Los Angeles Times, Leonard Feather called Peter ...One of the emergent great guitarists. Peter also worked with Chick on the film score to the movie The Cat Chasers, starring Kelly McGillis.
