History Massy attended Chico State University, where she worked as a radio DJ at campus station KCSC and became interested in recording equipment and production techniques while also performing in local bands.
Massy's first project was in the mid-1980s as producer, engineer, and mixer for a compilation album titled Rat Music for Rat People, Vol. 3 on the CD Presents label. Acts featured included Adolescents, Raw Power, Doggy Style and Mojo Nixon. Next she produced the punk band Verbal Abuse for Boner Records, was an engineer on two projects for metal band Exodus, and co-produced the Sea Hags independent album with a young Kirk Hammett, a guitarist who had just finished recording the Master of Puppets album with thrash metal group Metallica. She also produced "Television, Drug of a Nation" by the Beatnigs, the former band of Michael Franti from the Disposable Heroes of Hiphoprisy's.
From Green Jellö to Tool In the late 1980s, Massy moved from San Francisco to Los Angeles and worked at Tower Records on Sunset Boulevard. At Tower she met the members of Green Jellö (later known as Green Jellÿ), a band from Buffalo, New York and recorded their debut album. After becoming a staff engineer at Larrabee Sound in West Hollywood, California, Massy was hired by Zoo Records/BMG to produce Green Jellö's major label debut album featuring members of a new Los Angeles group called Tool. On Green Jellö's Cereal Killer album, Tool's Maynard James Keenan sings on "Three Little Pigs", and Tool's drummer Danny Carey plays on the album. A relationship was begun between Massy and Tool leading to two recordings, Opiate and Undertow. Julio Iglesias, Seal, Skunk Anansie, Paula Abdul, Ryuichi Sakamoto and others. She worked with manager Gary Kurfirst on Irish rock band Cyclefly for Kurfirst's Radioactive Records. At Larrabee Sound, Sylvia connected with producer Rick Rubin and worked with him on several projects over seven years.
