There comes a point in most artists’ careers where they just don’t care about making records anymore. Or at least they don’t care about making records that their fans want to hear. They tour sporadically, playing the old songs to pay the bills. And they release new albums every five years or so because they feel it’s something they should do. Eric Clapton got to this point years ago, but on his 21st solo album, ‘Old Sock,’ he settles into not caring like it’s his full-time job these days.
