Jake Shimabukuro turns the tiny four-string ukelele into a powerful instrument.

Jake Shimabukuro may be the first jazz musician to gain a pop following via the Internet sensation Youtube.com. A widely seen video captures the Hawaiian-born ukulele master sitting on a rocky outcropping in Central Park’s Strawberry Fields as he turns George Harrison’s White Album classic “While My Guitar Gently Weeps” into a scorching solo tour de force. With nearly half a million visits, the four-minute clip served as a savvy preview of his first solo album Gently Weeps, which hit the stores last September. He makes his Peninsula debut on Sunday at Monterey Live.  

Over the past seven years, Shimabukuro has transformed the diminutive four-string uke into an infinitely pliable instrument, capable of generating everything from crunching, effects-laden rock to sensuously swinging jazz. Along the way he’s shared stages with a panoply of artists, including fingerstyle guitar star Kaki King, banjo master Bela Fleck, vocal wizard Bobby McFerrin, mandolin virtuoso Mike Marshall and fiddle renegade Darol Anger.

Shimabukuro isn’t a jazz musician per se, though jazz is certainly one facet of his ever-expanding musical persona. A gifted improviser who is perfectly comfortable reharmonizing American Songbook standards, Shimabukuro is a dues-paying member of what Fleck calls “the odd instrument club,” a loosely affiliated group of musical explorers determined to turn theirs axes into all-terrain vehicles.

“Guys like Bela Fleck, Mike Marshall, Darol Anger, and Victor Wooten, they just take their instruments and run with it,” Shimabukuro said. “They don’t let anyone tell them, ‘You can’t do that.’ They find a way, and that’s what it’s about. You have the desire, you have that passion and you find a way to make it work.”

In a conversation last spring in San Francisco, Shimabukuro was still buzzing from four non-stop days of making music at the New Orleans Jazz & Heritage Festival. “I got to sit in with a lot of Dixieland bands, and I played with Jimmy Buffet in front of 120,000 people,” said Shimabukuro, grinning at the memory. “I played at the House of Blues with Keller Williams and I opened for The Radiators and then got to sit in with them. I also opened for Ivan Neville. Man, talk about the funk! We crammed three weeks of stuff into four days.”

 New Orleans is just the latest pinnacle in a career that’s been on a rapid upward climb since the summer of 2002, when he signed with Sony’s Epic Records International, a label with a strong presence in Japan. Shimabukuro has won a huge Japanese following through more than two dozen tours of the country. And he became a hometown hero when his first CD, Sunday Morning, won Instrumental Album of the Year at the 2003 Na Hoku Hanohano Awards (Hawaii’s Grammy), where he was also named Favorite Entertainer of the Year, honors he repeated in 2004 with his second album, Crosscurrent.

More importantly, Shimabukuro’s status in the unofficial but tight-knit fraternity of maverick string players was cemented when Bela Fleck asked him to record on the Flecktones’ album Little Worlds, and then invited him to tour with the band as an opening act. For fiddler Darol Anger, Shimabukuro represents the latest champion “bringing the string community back into the forefront of modern music.”

“Jake is a complete genius on the uke,” says Anger, who has nurtured several generations of brilliant string players. “It just makes me so happy to hear him. There are virtuosos who make you feel, ‘Oh God, I’ll never be able to do that,’ and there are virtuosos who make you happy to be alive. Jake is one of those people who make you happy to be alive, which is the highest compliment I can give to any musician.”  

Shimabukuro’s previous releases, like 2005’s Dragon, tended more toward instrumental pop than jazz. But when Shimabukuro performs on the mainland under his own name, he’s generally working solo, which is the context in which he’s the most dazzling. While he spent several years experimenting with effects and electronics, he’s returned to his acoustic roots, displaying his seemingly casual virtuosity in an unplugged contest. Rocking back and forth on his heels and swaying from side to side, he seems to enter another world as he plays a mix of original pieces and standards, his wrist moving at a hummingbird blur.

 “In the last several months I’ve become a purist,” Shimabukuro said. “I found myself relying so much on my effects to fill up the sound and to keep the show interesting. I wanted to break away from that and learn how to play my instrument again, because that’s what it’s all about.”

Shimabukuro’s new album, Gently Weeps, is a jazz-inflected statement that he feels will mark the end of one phase of his career. Instead of constantly making a case for his instrument’s rightful inclusion, he wants to focus on producing and composing. He hopes to work on film soundtracks and collaborate with vocalists, ambitions that go far beyond gaining recognition as the baddest ukulele player on the planet. Looking at the role models he’s chosen, Shimabukuro is on the right track.
