Thomas Wesley Pentz (born November 10, 1978), known professionally as Diplo, is an American DJ and music producer. He is a co-creator and lead member of the electronic dancehall music project Major Lazer; a member of the supergroup LSD, with Labrinth and Sia; a member of electronic duo Jack Ü, with producer and DJ Skrillex; and a member of Silk City, with Mark Ronson. He founded the record company Mad Decent in 2006 and the nonprofit organization Heaps Decent in 2007. His 2013 extended play (EP) Revolution debuted at number 68 on the US Billboard 200. Its title track was later featured in a Hyundai commercial and appears on the WWE 2K16 soundtrack.

Diplo worked with and dated British musician M.I.A., producing her 2008 breakout single "Paper Planes", which gave him initial mainstream exposure. In 2011, he and fellow producer Switch formed the electronic musical group Major Lazer and its namesake cartoon series for FXX, which ran for one season. The group released five studio albums that explored EDM and dancehall music, pioneering a new musical genre, ReggaeEDM. Since then, Diplo has produced for and collaborated with many mainstream musical acts, including Blackpink, Jennie, Lil Peep, Gwen Stefani, Die Antwoord, Britney Spears, Madonna, Shakira, Beyoncé, Ellie Goulding, the Weeknd, No Doubt, Justin Bieber, Usher, Anitta, Snoop Dogg, Trippie Redd, Chris Brown, CL, G-Dragon, Bad Bunny, Kali Uchis, Joji, Morgan Wallen, Bailey Zimmerman, MØ, and Poppy. His alias, short for Diplodocus, derives from his childhood fascination with dinosaurs.

Thomas Wesley Pentz was born on November 10, 1978, in Tupelo, Mississippi, the son of Barbara Jean (née Cox) and Thomas Pentz. He is of German and English descent.

Home-grown rap shaped Diplo's production style. Though born in Mississippi, he spent most of his youth in Miami, where he got a taste for the characteristic Miami bass. He began attending the University of Central Florida in 1997. During his time at UCF, he became a DJ at local radio station WPRK, at Rollins College. He moved to Philadelphia to continue his studies at Temple University, where he first drew attention as a DJ. At age 20, Diplo moved to India, with a small bag and barely any money. He purchased a used Enfield Motorcycle and traveled in Ladakh, Uttarakhand, West Bengal, and Gujarat. While in India he collected records, and visited rundown establishments to listen to people playing the sitar and tabla.^{[citation needed]}

After returning to the U.S. he became acquainted with fellow DJ Low Budget. The two began throwing parties under the "Hooked on Hollertronix" moniker in 2003 as a way to maintain control of what they could play during DJ gigs in Philadelphia. The success of these parties allowed the two to release mixtapes, both separately and together, gathering acclaim nationwide. One of these, Never Scared, was named one of The New York Times' top ten albums of 2003, and the Hollertronix name became synonymous with parties featuring guests like Maluca Mala, Bun B, Spank Rock, and M.I.A. Hollertronix's sound has been described as "disparate genres to be smashed together for maximum attention-grabbing impact", an aesthetic inspired by the "organic, cohesive, whole" aesthetic of acts such as Bun B, Lil Jon, Drama, M.I.A., Björk, and Busta Rhymes.

Diplo eschewed the club aesthetic of his Hollertronix music for a more reflective sound on his solo debut, Florida, which was released on the Ninja Tune imprint Big Dada Records. Florida was pressed twice, first as a CD and then as a CD/DVD Set. The DVD was put together by artist and filmmaker System D-128, who has also collaborated with Diplo on audio and film projects. Before Florida's DVD accompaniment, another DVD, Diplo: "Banned in Libya", was released by Money Studies, the first label to release a solo project by Diplo under his original DJ name, Diplodocus. It was a 45 rpm record called "Thingamajawn" for which there is also a video System D-128 directed. Like the Florida DVD, "Banned in Libya" is an experimental audio and video mix of Diplo's original music blended with a number of other unidentified sources. His affinity for the genre of baile funk, or favela funk, spawned a series of mixtapes (Favela on Blast, Favela Strikes Back), which brought the Brazilian dance music of the ghettos to the United States.

It was not long before his Hooked on Hollertronix parties gave him the success necessary to build a studio where music became his full-time focus. With this goal in mind, Diplo built "The Mausoleum", a video studio, recording studio, record label office, gallery, and event space in Philadelphia. Artists such as Christina Aguilera, Shakira, M.I.A., Santigold, Spank Rock, Plastic Little, Blaqstarr, and Paper Route Gangstaz have recorded at The Mausoleum. It has also hosted concerts by Glass Candy, Skream, Boys Noize, and Nicos Gun.

After hearing one of his songs in 2004, M.I.A. approached Diplo when he was DJing one night at the Fabric Club in London. Coincidentally, Diplo was playing her songs "Galang" and "Fire Fire" as she entered the club, which he got from a worker at i-D magazine. Diplo added, "She came through and she wanted to meet me 'cause she'd heard my single and the funk mix from one of her A&Rs and she just thought I was right up her alley. Besides me being a white dude from Florida and her being a Sri Lankan girl in England, everything else was the same: [We were both] film graduates, [listened to] all the same music when we were kids, we're going in the same direction right now in music, it was amazing. ... I always wanted to make a beat with her, but all my beats were really shitty at the time."
