National Skyline is an American alternative rock band formed in late 1996 by Jeff Dimpsey of Hum. Dimpsey originally formed the band in order to perform a 45-minute-long song that he had written. They were initially an indie rock supergroup of sorts, with a rotating cast of prominent Champaign/Chicago area musicians. They did record the 45-minute song/album with Rick Valentin in spring 1997, but it has never been released. The band's name is apparently a reference to Bob Dylan's album Nashville Skyline, though their music betrays no stylistic debt to Dylan.
