At LACMA, the New York New Music Ensemble took “Elektro Akoustiks: The New Tradition” to title its local visit, but in a sequence of short works by Jonathan Harvey, Eric Chasalow, Ezequiel ViƱao and Mathew Rosenblum, ending with David Felder’s Partial [dist] res[s]toration, I found that the cute orthography far outweighed any strength of spirit in the music, or any joy in performing it. Two nights later, the EAR Unit, with its usual kind of joyous perusal — above all of two strong works by the late (and much-missed) Earle Brown — restored confidence that there is still something to be said these days in music’s varied realms, and still some pleasure in the act of saying it.
