My Biography

Da Mouth of Madness. A name that has been around since the very beginning of hardcore. A voice that collaborated with almost every major hardcore DJ/producer. A laugh that still, after so many years, is instantly recognized on the dance floor. A man that has seen it all, done it all and still has more in store for y’all.

Sietse van Daalen first appeared as MC at the side of DJ Uzi, way back in 1994. The two young guns came from playing hiphop in the north of Holland. They found their new love in the harder styles of house that became popular around that time. After playing gigs in the region, they performed at one of the infamous ‘Thunderdome On Tour’ events in 1995. They made a lasting impression on Sander Groet, one of the organizers at ID&T. ID&T being hot, happening and on the road to the top they are now on, made it for Uzi & Da Mouth possible to spread their form of art throughout the nation, even Europe! With raves like Thunderdome ’96, Mysteryland and The Love Parade, they quickly made a name for themselves.

Next to performing live on stage, or doing what he does best in the studio, Da Mouth of Madness has also been on national television. As the anchorman of ‘TMF Hakkuh’ in 1997, he introduced legendary names like Buzz Fuzz, Dano, Darkraver, Neophyte, Rotterdam Terror Corps and many more to the big audience. Later that year MC Drokz joined him as host of the show.

Meanwhile, Da Mouth was working hard on his solo career. His resume is pretty impressive, to say the least. Hosting parties like Thunderdome, Qlimax, DefQon.1, Masters of Hardcore, Hellraiser, Qlub Tempo, HouseQlassics and much more, you can truly state that Sietse has been one of the leading MC’s in the history of hardcore. For a short while he was the MC of ‘Straight on Recordings’, owned en operated by DJ Pila & Luna.

Across the Dutch border, he also rocked raves like the Street Parade and The Energy Rave in Zurich. He’s a regular at events in Moscow, St. Petersburg, Glasgow and other major cities. Rockin’ it hard on an international level, that’s what Sietse does best.

Da Mouth of Madness can also be heard every wednesday night, together with fellow artists MC Justice and DJ Terminal. Together they give you Thunderdome Radio, the most infamous hardcore show on the world wide web. A place for young talent, big artists, general nonsense and the very best hardcore has to offer. Thunderdome Radio has become an institution over the past years, with a devoted fan base.
