...from early 1966, please enjoy The Rising Sons, featuring Taj Mahal and the teenaged Ry Cooder, and their spine-tingling "2:10 Train." Unplugged, as they say, before the word had been coined.
The Rising Sons -- the other big L.A. rock band of the 60s fronted by an African-American -- were immensely popular in their hometown between 1964 and '66, but they only released one single during their lifetime (a Lovin' Spoonful-ish cover of Mississippi John Hurt's "Candyman," which I actually had a white label promo copy of back in the day, although I lost it years ago). Incredibly, this cut -- which I think would rightly be considered one of the absolute landmarks of 60s folk/blues rock had it been released at the time -- was allowed to sit, unheard, in the Columbia Records vaults until 1992, when somebody finally had the bright idea to put out the CDs worth of stuff the band recorded during its brief run. (Said stuff, including "2:10 Train," was all produced by the late great Terry Melcher, of Byrds and Paul Revere and the Raiders fame.)
It's an amazing album, actually; you can -- and absolutely should -- order it HERE.
Oh, incidentally the song itself was written by an L.A. folkie named Linda Albertano, about whom I can find nothing other than that she must have known Linda Ronstadt, who also recorded it on the first Stone Poneys album.
