“On the day I was born, said my father, said he / I’ve an elegant legacy waiting for ye,” sings Milwaukee-born Al Jarreau on his hit song “Look to the Rainbow.” Elegance is one way to put it—longevity is another, and this jazz artist’s vocals are not to miss. Joining him in the act is multi-instrumentalist George Duke, best known for his fusion-filled collaborations with Frank Zappa. The smooth-fusion stalwarts are ready to shake up more than just “heaven and earth” on Saturday, Aug. 11, at Rodney Strong Vineyards. 11455 Old Redwood Hwy., Healdsburg. 5pm. $50—$80. 707.869.1595.
