John Mayer, who has won three Grammys and a jillion hearts with his wordy James Taylorishness, has gone trio, enlisting bassist Pino Palladino (the Who) and drummer Steve Jordan (Springsteen) to help channel his inner Clapton. Besides his own blues-rock tunes, Mayer tackles Ray Charles and Jimi Hendrix. (Yes, he’s bluesy and ballsy!) If JMT turns fans on to the blues, cool. If they’re already into it? Well, they probably won’t turn Try! John Mayer Trio Live in Concert on.
