In 2007, the E-bow was featured very prominently in the soundtrack for Ken Burn's documentary, The War. Doug Wamble performed a haunting slide guitar solo in the piece "Movin' Back", which was a mix of harmonic and primary tone E-bow soloing on an acoustic with a magnetic pickup. Wikipedia

The EBow is used in the musicals Wicked and Mary Poppins orchestrated by William David Brohn. In the Los Angeles production of Wicked, the EBow is played by Paul Viapiano.
