Music Adler's career in music began as co-manager, alongside
Herb Alpert, of
Jan and Dean. Adler and Alpert transitioned from managing into songwriting, composing the songs "River Rock" in 1958 for Bob "Froggy" Landers, and the Cough Drops and "
Wonderful World" with
Sam Cooke. In 1964, Adler founded
Dunhill Records. He was president and the chief record producer of the label from 1964 to 1967. During that time, Adler signed
the Mamas & the Papas to Dunhill, producing six top-five hits for the group including "
California Dreamin'" and "
Monday, Monday". Dunhill also reached No. 1 on the pop chart with
Barry McGuire's single "
Eve of Destruction". Capitalizing on Dunhill's success, Adler sold the label to
ABC in 1967 and founded
Ode Records, to which he signed
Carole King,
Spirit,
Cheech & Chong,
Scott McKenzie,
Peggy Lipton, and others. Adler produced all of King's albums on Ode, which includes four gold, a platinum, and a diamond album, as certified by the
RIAA. King's second album for Ode,
Tapestry, sold more than 25 million copies worldwide and is considered one of the greatest albums of all time. as well as the film version,
Monterey Pop, which he co-produced with
John Phillips from the
Mamas & the Papas. In 1975, Adler served as executive producer of the cult classic
The Rocky Horror Picture Show. After seeing
The Rocky Horror Show at a theater in
London, Adler bought the American rights to the show, presented it live in Los Angeles, and executive-produced the film version (adding "Picture" to the title). The movie became the longest-running theatrical film in history. In 1978, Adler directed the movie
Up in Smoke, starring
Cheech & Chong. The movie remains a cult hit, and in 2000 Adler and
Cheech Marin recorded a commentary track for the DVD release. His 1981 film,
Ladies and Gentlemen, The Fabulous Stains, did not make a large impact upon release but has enjoyed a long life on cable TV broadcasts. Also in 1981, Adler executive produced the follow-up to
The Rocky Horror Picture Show,
Shock Treatment. ==Personal life==
