In addition to his contributions to jazz, he has made his mark on pop culture, serving as music coach and guitar instructor to the young actors on Nickelodeon's popular series The Naked Brothers Band.
He soon became determined to own an electric guitar and took lessons at a local music store in Fountain Valley, later earning enough pocket money to purchase a Fender Stratocaster.
Joining the band of the popular American trombonist/vocalist Gene "Mighty Flea" Conners, Spiegel performed concerts throughout Germany, Switzerland, Austria, Belgium, and the Netherlands.
There he studied under teachers Adam Rogers, Paul Bollenback, Ben Monder and John Patitucci, receiving his master's degree in jazz performance from the City College of New York.
He was next cast as a musician in the film comedy What Happens in Vegas (2008), played a similar part in When in Rome (2010), and won a recurring, uncredited role in the TV series 30 Rock.
Spiegel has also composed music for the shorts Waterfront Access (2009), Psychobabble (2010), and I Am Julia (2011), as well as for the documentary Building Bridges (2011), about a group of high school students from New York who travel to India.
