Al Schmitt is a recording engineer and record producer.

Schmitt grew up in New York City. After serving in the U.S. Navy he began working at Apex Recording Studios at the age of 19. In the late 1950's Schmitt moved to Los Angeles and became a staff engineer at Radio Recorders on Santa Monica Blvd in Hollywood. In the early 1960's he moved to RCA in Hollywood as a staff engineer. While at RCA he engineered albums for Henry Mancini, Cal Tjader, Al Hirt, Rosemary Clooney, Liverpool Five, The Astronauts, Sam Cooke "Bring It on Home to Me" "Cupid" "Another Saturday Night" in 1961.

Bonnie Lynn Raitt (born November 8, 1949) is an American blues singer-songwriter and a renowned slide guitar player. During the 1970s, Raitt released a series of acclaimed roots-influenced albums which incorporated elements of blues, rock, folk and country, but she is perhaps best known for her more commercially accessible recordings in the 1990s including "Nick of Time", "Something to Talk About", "Love Sneakin' Up on You", and the slow ballad "I Can't Make You Love Me". Raitt has received nine Grammy Awards in her career and is a lifelong political activist.

Raitt, the daughter of Broadway musical star John Raitt and his first wife, pianist Marjorie Haydock, began playing guitar at an early age, something few of her high school female friends did. Later she would become famous for her bottleneck-style guitar playing. "I had played a little at school and at camp", she later recalled in a July 2002 interview. The camp Raitt refers to is Camp Regis-Applejack, located in the heart of the Adirondacks.
