The producer, dj and leader of Evil Activities , Kel van Soest, started his career in 1997. He was discovered by Jeroen Streunding (Dj Neophyte) and released his first record in the beginning of 1998 on the "Rotterdam Records" imprint. Almost a year later dj Neophyte launched his own label "Neophyte records" and for Kel it was a logic step to change labels.

Afer not long, Kel and Jeroen hit the studio together and that result was the resurrection of "Masters of Ceremony". Now after almost 9 years of hard work and dedication Evil Activities has worked with and remixed for hardcore legends like Dj Neophyte, Endymion, The Viper, Dj Panic, Nosferatu, Dj Jappo & Lancinhouse and Dj Paul Elstak. He has played at almost all big hardcore events across the globe and still continues to travel the world with his energetic dj and live act.
