Ralph J. Gleason
Two of those books--both on Ralph J. Gleason--just came out. That ball started rolling after I realized that Toby Gleason and I shared a Facebook friend. I asked Toby if he had ever considered producing an anthology of his father's key work. Long story short, that book (and a companion) just came out from Yale University Press.
The New Yorker was on the case. It posted a complimentary piece by Richard Brody and used the photograph above.
Baron Wolman, whom I interviewed for my book on the Grateful Dead, made the photograph. Today he told me he took it at a Mills College conference on rock and roll in 1967. That very day, Jann Wenner asked him to work at a new (and as yet unnamed) magazine. That magazine, of course, was Rolling Stone.
Update: My friend Michael Kramer tells me that Phil Spector and Tom Donahue were at that conference, too. Also that he's writing an article about it.
