If you were hoping to attend Moveon.org’s ‘Vote For Change’ megaconcert at the MCI Center on October 11, prepare to fork over some dough.

An email sent yesterday to MoveOn members registered for the pre-sale listed the prices as $90 and $175. The concert will feature Bonnie Raitt, Bruce Springsteen and the E Street Band, Dave Matthews Band, The Dixie Chicks, Jackson Browne, James Taylor, John Fogerty, John Mellencamp, Jurassic 5, Keb’ Mo’, Kenneth “Babyface” Edmonds, Pearl Jam, and R.E.M.

After providing elaborate instructions for the special invitation-only sale beginning at 10 a.m. today, the group assures us that

Remember, if you don’t get tickets this way, you’ll still have an opportunity to get them as a member of the general public. Tickets will go on sale to the general public on Saturday, September 18th at 10 AM ET at http://www.ticketmaster.com/voteforchange/ or by phone at 202-432-SEAT — no outlets.

The upper end of the range for the arena’s concert capacity is around 20,000, if this old Post article is to be believed.
