Answer by taking a quote from the following article:

Michael Kenji Shinoda (, born February 11, 1977) is an American musician, singer, songwriter, rapper, record producer and graphic designer. He co-founded Linkin Park in 1996 and is the band's rhythm guitarist, primary songwriter, keyboardist, producer, and lead vocalist. Shinoda later created a hip-hop-driven side project, Fort Minor, in 2004. He served as a producer for tracks and albums by Lupe Fiasco, Styles of Beyond and The X-Ecutioners.

Shinoda has also served as a music producer for several other artists and groups. In 2002, Shinoda and Joe Hahn collaborated with the X-Ecutioners to produce and perform on their single "It's Goin' Down". Later in 2002, Shinoda and Brad Delson established their own record label, Machine Shop Recordings. He helped produce Lupe Fiasco's 2006 release, Food & Liquor. He extensively worked with Styles of Beyond between 2009 and 2012 to help produce Reseda Beach, which also features his instrumental and vocal contribution. In addition albums, Shinoda scored the MTV VMA's in 2005 and also worked with Ramin Djawadi to score the video game, Medal of Honor: Warfighter. In 2011, he collaborated with Joseph Trapanese to compose the score for the American release of The Raid: Redemption. In 2004, he released a remixed single and animated music video of the 1990 Depeche Mode single, "Enjoy the Silence". In 2005, Shinoda hosted the Rock Phenomenon mixtape/remix CD with DJ Vlad and Roc Raida. The CD is the first (and to date, only) in DJ Vlad's Rock Phenomenon series (which itself is a spin-off of Vlad's Rap Phenomenon mixtape series), and features a mashup of Linkin Park's "Papercut", and David Banner's "Like a Pimp (Remix)". For the 2006 Grammy awards, Shinoda and Brad Delson assembled the mashup track of "Numb/Encore" and "Yesterday" by The Beatles to be performed live by rapper Jay-Z, Linkin Park and former Beatles singer Paul McCartney. Shinoda teamed up with former bandmate Mark Wakefield to record and release a single, "Barack Your World", in October 2008. Shinoda contributed to the music for the CNN original documentary television series, This Is Life with Lisa Ling. Shinoda contributed the title theme for American television series Into the Badlands. Shinoda also provided the theme song for Noor Tagouri's A Woman's Job.
