Tenacious D To Release Debut LP

Jack Black, Kyle Gass to drop self-titled CD in September.

Tenacious D, the self-proclaimed "Greatest Band on Earth," are finally set to inflict their debut CD upon the world.

The acoustic rock duo — Jack Black of "High Fidelity" fame and sidekick Kyle Gass — will unleash its self-titled effort on September 25. The disc will include the tunes "Lee" — an homage to the band's roadie — and "Tribute," both staples of Tenacious D's live shows and short-lived HBO series, according to Epic records.

The album, produced by the Dust Brothers and recorded in part at ArcAngel Studio in Los Angeles — which is owned by Tenacious D's idol Neil Diamond — will feature appearances by Dave Grohl of Foo Fighters (the duo appeared in the Foos' "Learn to Fly" video), Page McConnell of Phish and Steve McDonald of Redd Kross.

Tenacious D will hit the road for a fall tour, though no dates have been set.
