Dirty Disco is a moniker under which DJ/Producer Mark De Lange, a Houston-native, creates audio recordings, live DJ sets and specialized parties. It was originally founded by Veteran British DJ JD Arnold & Mark DeLange. ^[1]

Formed by Mark De Lange (aka DJ Mark D) to provide remix services and retool classics for his Dangerous Disco events at nightclubs he owns. It took off to such a degree that disco classics became less of the focus and more modern music as the word got out and he was solicited by record labels wanting such.

De Lange (DJ Mark D) began DJing in 1984 and has been the resident of Roxy, Club Pacific Street, Rich's, XM Satellite Radio (ch 81 BPM) and 104.1 KRBE radio. He now owns and operates nightclub/bar venues throughout Houston and surrounding areas. De Lange came upon with the name Dirty Disco as a play off the party name of Dangerous Disco.^[2] He's been hired on numerous remix projects including Casablanca's "Enough Is Enough 2017" Donna Summer & Barbra Streisand, Diana Ross's "Upside Down/Coming Out" 2018 mashup along with other artists like Enrique Iglesias, the Trash Mermaids, U2, Paris Hilton, GusGus, Olivia Holt, Janet Jackson, KC & the Sunshine Band, Kim Petras, Maroon 5, Carly Rae Jepsen and others. To date, Dirty Disco has had numerous Billboard No. 1 dance singles on projects they were hired on and have numerous Billboard top 5 singles on their proprietary record label Dirty Disco Music (DDM). He continues to produce dance singles at a record pace, sometimes a track or two a week along with music videos to accompany the work product. To date (2024) Dirty Disco has generated a catalog of over 8,000 mixes. De Lange was also a Billboard reporting DJ.
