By age 21, vocalist Colbie Caillat had evolved swiftly from an aspiring R&B/folk singer to a pop sensation, a feat that owed as much to the marketing assistance of MySpace as the meteoric popularity of her debut single, "Bubbly." Caillat's childhood was spent in Malibu and Ventura County with her father Ken Caillat, an established audio engineer who helped produce Fleetwood Mac's Rumours and Tusk. Songs were often mixed at the console in her Malibu beach house, filling the corridors with the sounds of Billy Idol, Pat Benatar, and other '80s pop/rock staples. Caillat took piano lessons as a child, but lacked significant inspiration until she turned 11 years old and became enthralled with Lauryn Hill's performance in Sister Act 2. Immediately realizing that she wanted to be a singer, she started taking vocal lessons and soon met Mikal Blue, a producer who had previously worked with Five for Fighting and Carrie Underwood. Blue hired her to sing on several techno songs that were to be used in runway models' shows, and the two cultivated a professional relationship. At 19, Caillat picked up an acoustic guitar, and the two recorded the first song she composed.
