Sargeant, Winthrop. “Musical Events: It Just Is-or Is It?” The New Yorker (September 14, 1963): 120-123.

Winthrop Sargeant's review, "Musical Events: It Just Is-or Is It?," was published  
 on September 14, 1963. In the article, Sargeant mentions Max Neuhaus as a highly skilled percussionist at a recent avant-garde concert.

The concert featured a program of contemporary music, where Neuhaus performed complex pieces by composers such as John Cage and Karlheinz Stockhausen. Sargeant's review provides insight into the critical reception of experimental music during that era and highlights Neuhaus's early career as a performer before he transitioned fully into site-specific sound installations
