Here's a good example of Leventhal's wide rnage as a terrific guitar player/multi-instrumentalist/composer/producer. From Shawn Colvin's "A few small repairs" - the Grammy winner produced by Leventhal. In this tune of his own composition he plays all guitar parts including the steel pedal and slides and he also plays the organ. To me, THAT is proper guitar pickin'. ymmv
