AN21 has collaborated with Max Vangeli on numerous projects, including an album called "People of the Night". He is known for his energetic musical style and performances at electronic music festivals around the world. Dimitri Vangelis is also a DJ and producer, but he forms a duo with Wyman, both of whom are from Sweden. The duo is well known for their progressive house productions and have collaborated with artists such as Steve Angello and AN21. They are renowned for their dynamic melodies and powerful beats. If you are referring to collaborations between AN21 and Dimitri Vangelis, it is possible that they have shared the stage or worked together on specific projects, particularly within the context of electronic music community collaborations.
