WHEN SESSIONS REIGNED SUPREME: THE PLAYERS, STUDIOS FROM L.A.’S GOLDEN AGE

The Record Plant in Los Angeles was the place to be on Sunday nights in 1973, when owner Gary Kellgren convinced drummer Jim Keltner to host a weekly jam session called the Jim Keltner Fan Club Hour—despite Keltner’s distaste for “jamming,” and for the moniker. So many huge artists played and recordings were made, though they never saw the light of day, except for one monumental evening Keltner recalls that was bootlegged for many years and finally released by Mick Jagger on the Very Best of Mick Jagger in 2007.
