Daniel Paul Federici (January 23, 1950 – April 17, 2008) was an American musician, best known as a founding member of Bruce Springsteen's E Street Band, where he was its organist, accordionist and glockenspiel player.

[1] During in-concert band intros, Springsteen often referred to him as "Phantom", sometimes said to be because of an incident in Asbury Park in the 1960s where Federici evaded a police crackdown that resulted in the arrest of numerous others.

The design is unique in that there are resonator tubes similar to those of vibes protruding vertically from the top in staggered lengths resembling calliope or organ pipes, amplifying the horizontal xylophone-like bell bars below which were struck by keyboard actuated hammers much like a piano's.

Federici's haunting accordion and B3 work became an integral component of their Southern Rock sound, and he co-wrote several tracks with lead singer Franklin Jenkins.

[4] On November 21, 2007, it was announced that Federici would take a leave of absence from Springsteen and the E Street Band's ongoing Magic Tour to pursue treatment for melanoma, and was temporarily replaced by veteran musician Charles Giordano.

[9] On July 15, 2008, Bruce Springsteen and the E Street Band, through Columbia Records, released an EP of audio and video tracks for digital download, entitled Magic Tour Highlights, with all proceeds going to the fund.

The tracks are taken from the Magic Tour, and feature a performance of "4th of July, Asbury Park (Sandy)" from Federici's final March 20 Indianapolis appearance with the band.
