"Several jazz labels are grouped under the umbrella of Cologne's "Deutschen Media Productions GmbH & Co Kg," among them Between The Lines (founded 1999, 46 titles), but above all Double Moon (founded 1998, 91 albums) under the leadership of Volker Dueck, with a clear focus on young German jazz."

"1994 was also the year in which Hein co-founded with Anne de Jong and Joost Leijen the Jazz label Challenge Records, for which he has produced, and is still producing, a growing number of successful recordings. Two of them in fact received an Edison (Denise Jannah in 1994, Eric Vloeimans in 1999) for best recording of the year. In 2004 Hein became the sole owner of Challenge Jazz Records and is slowly expanding the catalogue."
