A 21st-century ukulele prodigy whose fretwork blows past the instrument’s renown as a low-key Hawaiian music staple, Jake Shimabukuro has taken the sound into rock and jazz with panache. Nashville Sessions sees Shimabukuro’s band pushing themselves to the outer limits of improv on furious and free-flowing cuts like “6/8” before just as easily pulling off contemplative instrumentals like “Blue Haiku.” Between these 11 explosive tracks, Shimabukuro seems to suggest that the ukulele is just as capable of melting faces as the guitar.
