Cut Chemist (born Lucas MacFadden October 4, 1972)is a former member of the funk Latin band Ozomatli, and of hip hop group Jurassic 5. He has collaborated with fellow turntablist DJ Shadow on a number of projects. MacFadden became known through the Los Angeles-based rap group Unity Committee, and debuted on vinyl on the B-side of Unity Committee's 1993 single, "Unified Rebelution". The track, "Lesson 4: The Radio" was an ovation of Double Dee and Steinski's "Lessons 1-3." Preceding the vinyl release, Unity Committee formed Jurassic 5, along with another group, Rebels of Rhythm. McFadden contributed avidly to the group, adding "Lesson 6.
The Lecture" to Jurassic 5's eponymous EP, and co-producing the entirety of the record. Between then and other releases, he explored remixing alongside DJ Shadow and Liquid Liquid, and performed doing outside work (sampling and scratching for Less Than Jake, and appearing with Ozomatli). From late 1996 to early 1997, Cut Chemist recorded his album debut, Live at Future Primitive Sound Session, with Shortkut of Invisibl Skratch Piklz. According to the official Jurassic 5 website, McFadden did not appear on their most recent album Feedback. In May 2006, he indicated to Billboard magazine that he has left the group.
McFadden's first full-length solo album, The Audience's Listening, was released on July 11, 2006. The album includes the pre-released song "The Garden", which features a bossa nova style, vocals from Astrud Gilberto's Brazilian song "Berimbau", and berimbau instrumentals. The song "The Audience Is Listening Theme Song" from The Audience's Listening has recently been featured in a 2G Apple iPod nano advertisement. More recently, McFadden has opened for Shakira in 2007 on the European leg of her Oral Fixation Tour, and at the press conference held by car-maker SEAT to promote their sponsorship of the shows. Cut Chemist has also produced the track 'Radio Friendly' for Canadian rapper Abdominal's solo album. Cut Chemist made an appearance in the 2007 comedy Juno, playing a high school chemistry teacher, playing on his "chemist" stage-name. Cut Chemist joined DJ Shadow on a world wide tour to support their new mix "The Hard Sell" beginning in early 2008. Kid Koala will also be touring and opening for them. Dates include Dallas, New York, San Francisco, Melbourne, Toronto, Vancouver, London, Hamburg and Paris among others. Cut Chemist's video for the song "What's the Altitude" featuring Hymnal has 93,619,283 views on YouTube as of December 11 2008, but it is not listed on YouTube's list of most-viewed videos. Cut Chemist is featured in the award-winning documentary "This is the Life (film)," chronicling the music movement which was birthed at The Good Life Cafe in South Central Los Angeles. The Good Life is the open-mic workshop where he first performed with Unity Committee in the early 1990s and launched Jurassic 5.
