Freddie King opening for Elvin Bishop (if you think it should’ve been the other around, I agree). I was in high school -- it was either ’73 or ’74. That was some of the most intense Blues guitar playing I’ve witnessed in person, culminating in "Goin’ Down". I know Blues scholars prefer his earlier work with the cleaner-sounding P90 equipped Gold Top, but not me. I like the nastier tone he sported later on, with those big ol’ semi hollows and more gain. There’s a youtube video from some outdoor gig in Texas, I believe, from around that time, with a great version of "Ain’t Nobody’s Business". My favorite of the three Kings.
