I always have the same sequence of feelings at every Keller Williams show I attend; "Yeah, I’'m here, so what?" indifference followed by grin-busting enchantment and laugh-out-loud delight. The unassuming leader of the jam scene’s one man-band phenomena sings, plays a myriad of instruments (though acoustic guitar is his standby) and dips into a wide pool of genres – rock, bluegrass, dance music, funk, folk, jazz and reggae – as he charms with his quirky lyrics and sunny upbeat strums, picks, plucks, taps and slides. This year, the songsmith issued Pick, an album of originals and covers performed with The Travelin' McCourys. Most likely this performance will be a combo of straightforward acoustic axe playing and ADD-riddled looping of vocals and instrumentals on any of the array of stringed instruments scattered across the stage.
