Stills

On May 4, 1970, National Guardsmen squared off against anti-war demonstrators on the campus of Ohio’s Kent State University.

Call it luck or great planning. All four members of Crosby, Stills, Nash & Young will be together again on Oct. 26-27 for the Bridge School Benefit Concert in Mountain View, Calif. The show will no doubt whet the appetite of fans of the band, especially those anticipating a 40th anniversary tour in 2014.

Crosby, Stills & Nash fans are all too aware of how the best-laid plans can often go awry -- and in the case of the upcoming live album drawn from a 1974 tour with the trio's on-again, off-again collaborator Neil Young, those plans appear to have changed once again.

Crosby, Stills & Nash will give fans an encore of their critically acclaimed 2012 tour this spring and summer, although you may need to travel to see the trio play. The rockers have announced 23 shows for 2013, including 13 in the southeastern United States and 10 in Europe.
