Career Olsen was born in Sioux Falls, South Dakota, United States, and went to school in Minneapolis, where he developed an appreciation for classical, pop, and jazz music. He gained production experience working in recording studios in the Minneapolis area, and musical and touring experience playing upright bass in jazz and folk bands. He subsequently played bass as a member of the Music Machine, who had a hit with the single "Talk Talk". During this time he began collaborating with Curt Boettcher, producer of the Association's single "Cherish", and met another early influence, Brian Wilson of the Beach Boys, who taught him "to envision everything about a production as you hear the song the first time." After moving to Los Angeles he was instrumental in launching the careers of Lindsey Buckingham and Stevie Nicks. He helped them to secure a record deal, produced their first album, Buckingham Nicks, and let them live in his house, employing Nicks as a housekeeper for a while. After introducing them to Mick Fleetwood, he went on to produce Fleetwood Mac's eponymous 1975 album, which reached No. 1 in the US. Through the 1970s, 1980s, and 1990s, Olsen built a reputation as a producer. In addition to Fleetwood Mac, some of the artists he has worked with include the Grateful Dead (he produced and engineered their 1977 album Terrapin Station); Bob Weir; Eddie Money; Emerson, Lake & Palmer; Rick Springfield (he produced Springfield's No. 1 hit "Jessie's Girl"); REO Speedwagon; Pat Benatar; Heart; Joe Walsh; Starship; Santana; Kim Carnes; Sheila; Jethro Tull; The Babys; Magnum (Goodnight L.A.); Saga; Ozzy Osbourne (No Rest for the Wicked); Scorpions (Crazy World); Bad Company; Europe; 38 Special; Russ Ballard; Sammy Hagar; Whitesnake; Foreigner; Sheena Easton; Steve Perry; Journey; Loverboy; and Lou Gramm.
