We may not have the leaves changing colors, but we have a lot of shows to hold us over in the fall. First up this week LA has two singers who can carry a note on their back through the Sahara without breaking a sweat. Colbie Caillat will be at John Ford bringing her signature California beach sound to the stage, and a couple of days later Alessia Cara will be at The Wiltern. Don’t know her? Then you’re one of the few. Her single “Here” for her insane amounts of attention over the past year as he continued to rise to the top. Look out for her to win a Grammy or two next year. The next night funk meets soul meets fun by way of Fitz And The Tantrums will be at the Greek. Then we’ll round out the week with Gwen Stefani taking over the Forum for a couple of nights, and Green Day coming back to the scene at the Palladium.
