Hämmerklavier' is a full-length cyclical work. The composer tries casting off the straight-jacket of hide-bound musical traditions, sending the listener on a voyage of discovery and liberation. The 'Hämmer' of the title refers not to the action of the pianoforte nor to Beethoven's 'Hammerklaviersonate' but to the mental approach required of the performer who needs to be a true 'performance artist'. The composer has recorded the entire cycle for WERGO (WER 6611-2).
