This summer keeps getting bigger for Red Rocks. Crosby, Stills & Nash added Colorado's music mecca to their tour calendar.

In a slew of new dates announced on top of the concerts already schedule for July, the trio is topping the whole thing off with a Sept. 23 appearance at Red Rocks. No, there will be no Neil Young, but the press release says they'll be playing some solo material in addition to their collaborative songs.

Tickets got on sale at 10 a.m. Friday for $49.50-$99.50.
