This fall Jake Shimabukuro will embark on a 30-plus city tour, performing solo for the most part. Shimabukuro’s new record, Grand Ukulele, feels like the next step in a career that really started at the age of 4 when he first picked up the instrument, through a successful local career in Hawaii and his first brush with fame on YouTube. Now, he’s a respected, popular musician looking to make a lasting musical mark. With Grand Ukulele, Shimabukuro’s star may burn even brighter.
