In today’s mail: Paperback editions of Sharon Lee and Steve Miller’s “Neogenesis” and Eric Flint and Charles Gannon’s “The Vatican Sanction.” Also: the 2016 Celebration of Joan Baez’s 75th birthday, complete with a whole bunch of guest artists singing with her.

Here’s one of the songs: Baez and Mary Chapin Carpenter singing Donovan’s “Catch the Wind.”

Here’s another: “Deportee,” an old Woodie Guthrie song sung by Baez, Jackson Browne and Emmylou Harris.

Did you know that Jackson gave the induction speech for Joan at the Rock and Roll Hall of Fame in 2017?
