Upon leaving Ruthless and forming Death Row Records in 1991, Dre called on veteran West Coast DJ Chris "The Glove" Taylor and sound engineer Greg "Gregski" Royal, along with Colin Wolfe, to help him on future projects. His 1992 album "The Chronic" is thought to be one of the most well-produced hip-hop albums of all time. Musical themes included hard-hitting synthesizer solos played by Wolfe, bass-heavy compositions, background female vocals and Dre fully embracing 1970s funk samples. Dre used a minimoog synth to replay the melody from Leon Haywood's 1972 song "I Wanna Do Somethin' Freaky to You" for the Chronic's first single "Nuthin' but a "G" Thang" which became a global hit. For his new protégé Snoop Doggy Dogg's album "Doggystyle", Dre collaborated with then 19-year-old producer Daz Dillinger, who received co-production credits on songs "Serial Killa" and "For all My Niggaz & Bitches", The Dramatics bass player Tony "T. Money" Green, guitarist Ricky Rouse, keyboardists Emanuel "Porkchop" Dean and Sean "Barney Rubble" Thomas and engineer Tommy Daugherty, as well as Warren G and Sam Sneed, who are credited with bringing several samples to the studio.
