The new album by the Karl Seglem & Christoph Stiefel Group, Hopp (and Smile) and Monsterjazz, is presented in two separate parts as a double CD. The first CD is entitled Hopp (and Smile) and although it is based on how children experience music, it is explicitly aimed at the experienced listener. Here, the clarity of the playful sequence is at least as important as the immediate expressive impulse. The second CD, Monsterjazz - An Interactive Jazz Journey For All Ages, contains the Monsterjazz program for children. Seglem and Stiefel, together with singer Jullie Hjetland Jensen, bassist Trygve Waldemar Fiske and drummer Kare Opheim, succeed in making the performance character audible in an exemplary way on their double CD. Christoph Stiefel and Karl Seglem succeed in opening jazz up to new listeners and perspectives.
