Sponsoring 'Our America' as a free download.

In its continued partnership with Big & Rich and Gretchen Wilson, Chevrolet is a presenting sponsor of "Our America," a new recording by Big & Rich, Wilson and Cowboy Troy.

Between July 1 and July 5, "Our America"--a musical marriage of "The Star Spangled Banner," the Preamble to the Constitution and Martin Luther King Jr.'s "I Have a Dream" speech--will be available as a free, timed-out download at ouramerica2005.com. The download can be listened to until Sept. 5.

The Muzik Mafia quartet will perform "Our America" live with the Boston Pops July 4 during the annual Boston Pops Fireworks Spectacular at the Charles River Esplanade in Boston. The event will air live on CBS at 10:00 p.m. EST. Harry Smith ("The Today Show") and Jann Carl ("Entertainment Tonight") are confirmed to host the broadcast.

Later this year, "Our America" will re-surface on sophomore releases from Big & Rich (Warner Bros.) and Wilson (Epic).
