John Rockwood was there with his fast shutter: a line-up of guitars on the long-gone urinals of the Toledo Sports Arena, Jimmy Reed in a wig hat, 17-year-old Tanya Tucker on her first tour, Jon Hendricks backstage bending notes, Muddy Waters holding court, Toledo icons Art and Roman Griswold with Big Jack Reynolds at a long-shuttered joint near the Maumee River. Rockwood got that clean shot of Son House calm and elegant, Jethro Tull, eyeballing his sexy backup singers, BB King chillin' in the dressing room, sweat-drenched Lil' Ed fronting the Blues Imperials at Toledo's Party in the Park. Rockwood caught John Lee Hooker jamming and Bo Diddley prancing, Dave Brubeck like a sphinx arched over the keys, Springsteen in a black muscle shirt by half-light, James Brown performing in a cheerleader skirt, Victoria Spivey glancing at Johnny Ace in Ann Arbor, and Jerry Lee Lewis, "The Killer," absolutely destroying 88 keys. Then and there and here and now - this is John Rockwood's astounding, vast contribution to our American Archive.
