At the time of this 1964 event, Neuhaus was primarily known as a virtuoso percussionist. This recital took place during his tenure as a pioneering interpreter of Stockhausen's complex and aleatoric compositions.
The "evening" highlighted works such as Zyklus for solo percussion, a piece that requires the performer to stand at the center of a circle of instruments, and Refrain. Barbican: Stockhausen. Ericson's review captured the New York audience's reaction to Stockhausen's radical ideas about serialism and the physicality of sound. Interior Spaces Stockhausen.
