Caillat was born in Malibu, California, and grew up in Newbury Park, California. Her father, Ken Caillat, co-produced Fleetwood Mac's Rumours (1977) and Tusk (1979) albums. When she was an infant, her parents gave her the nickname "Coco", which she would later name her debut album. Caillat took piano lessons as a child, but lacked significant inspiration until she turned 11 years old, when she became enthralled with Lauryn Hill's performance in Sister Act 2. She realized that she wanted to be a singer, and began taking vocal lessons, performing onstage for the first time in sixth grade. Since then she has covered the Roberta Flack song that Lauryn Hill immortalized, "Killing Me Softly", and Hill's own^{[citation needed]} "Tell Him" (an import bonus song from her solo debut album).

Lester William Polsfuss (June 9, 1915 – August 13, 2009)—known as Les Paul—was an American jazz and country guitarist, songwriter and inventor. He was the inventor of the solid-body electric guitar which made the sound of rock and roll possible. He is credited with many recording innovations. Although he was not the first to use the technique, his early experiments with overdubbing (also known as sound on sound),delay effects such as tape delay, phasing effects and multitrack recording were among the first to attract widespread attention.

His innovative talents extended into his playing style, including licks, trills, chording sequences, fretting techniques and timing, which set him apart from his contemporaries and inspired many guitarists of the present day. He recorded with his wife Mary Ford in the 1950s, and they sold millions of records.

Among his many honors, Paul is one of a handful of artists with a permanent, stand-alone exhibit in the Rock and Roll Hall of Fame. He is prominently named by the music museum on its website as an "architect" and a "key inductee" along with Sam Phillips and Alan Freed.
