His wonderful, classic book on country music improved and enriched my relation to that whole genre of music, forever. More recently, I got a huge kick out of his expertly done survey of Texas musicians. But above and beyond all that, everything I read by him, starting with the earliest issues of Rolling Stone that I can remember, affirmed that it was plenty possible to be a good-hearted person and write with passion about pop. Here’s a fine interview. And here’s a link to some of his more recent work. Jerry Lee is certainly a spiffy one to to go out on.
