I worked with JohThema Promotion and directly with Jan Janssen to promote my latest album, BARTOK. Jan put a lot of time, energy, and dedication into the project, and his work was truly outstanding. I really enjoyed working with him. The album and the whole project received great visibility, and Jan proved to be a highly professional, reliable, and dedicated promoter. I would definitely be happy to work with him again in the future, and I highly recommend his work. (Marco Bartoccioni – BARTOK)
