Current Album


The new album BASSMASSE 13 / 45 presents, on the one hand, studio and live recordings of his ensemble BASSMASSE 13 (with 13 bassists), as well as excerpts from the already legendary opening concert of the Moers Festival 2014 with nearly 50 double bassists.

With the release of BASSMASSE 13 / 45, the two-time ECHO award winner (double bass - national) brings his diverse activities around his body instrument to a temporary climax.

Here, on the one hand, BM 13 shows itself as a compact, perfectly recorded "pocket orchestra" in contrast to the orchestral fireworks of BM 45. For the listener, the different interpretations of the pieces "Bucolico" and "Kleine Koalition" of both ensembles are certainly highly interesting against this background.

"HIGHLIGHT: ... Between orchestral force of intimate interaction: large-volume basses and concise harmonics, cross-rhythms and finely tuned sound modulations, lively grooves and orchestral sound layering, the various facets were made audible in the frequency band of the many basses." - (Neue Züricher Zeitung)
