I found this clip through reddit.com, suspecting from the title that the player might be Jake. It was. We're lucky to live in Honolulu, Jake's home, so we've seen him countless times and he's always amazing. If anything, this video shows only a sliver of what he does so well. The instrument is an ukulele, which is as big in Hawaii as surfing and shave ice. However, if you like ukulele, please explore Hawaiian music, for you'll find all sorts of great players, from jazz soloists to Hawaiian groups. A typical ensemble might have a uke or two, guitar(s), and bass--all acoustic--with all the players also singing in close harmony, often in Hawaii's very distinctive falsetto style. My personal favorite group is Maunalua, a trio. Jake plays live in Hawaii, tours Japan, and probably the Mainland.
