The 35-date tour to be promoted by TNA Int'l.

An announcement is expected today regarding this summer’s Crosby, Stills, Nash & Young Freedom Of Speech tour, Billboard.biz has learned. The 35-date tour, promoted by TNA International, will begin July 6 at the Tweeter Center near Philadelphia, and run through Sept. 10 at the Post-Gazette Pavilion in Burgettstown, Pa.. The tour will play a mixture of amphitheaters and arenas.

Young will be touring in support of two albums, his acoustic “Prairie Wind” album released last September, and a politically-charged rock album “Living With War” due in mid-May.

There had been speculation that Young might tour with his rock band Crazy Horse this year, but a CSNY tour is always welcome, according to the tour’s promoter. “They’ve been talking about doing this on and off for a while, but it’s up to them when the stars all align and they decide to do it,” TNA President Arthur Fogel tells Billboard.biz. “I’m pretty excited they decided to go with this now. It has been four years since they’ve gone out, and this is one of those things when you get them all together, it’s pretty magical.”

Ticket prices will be “pretty similar to last time,” Fogel says, with prices topping out in $175-$250, depending on the market. Lawn and upper-tier arena tickets will be in the $30-$35 range. There will be a fanclub pre-sale later this week, and tickets will go on sale to the general public this weekend.

CSNY last toured in 2002, grossing more than $35 million, ninth best for the year, and drawing 438,022 from 40 dates. The CSNY2K tour in 2000, the group’s first as a foursome in 20 years, grossed $42 million.
