The Philip Glass Ensemble, led by longtime music director Michael Riesman, performs a 50th-anniversary concert with an Es Devlin installation at the Howard Gilman Opera House, November 19–21. The clean planning candidate is Saturday, November 21 at 7:30 p.m.; tickets start at $65, plus BAM’s listed fees. A Buy Tickets route is live, but I did not verify selectable seats. BAM
This is a catch-up discovery—the public sale began June 30—not a fresh drop. It survives the lateness because it is neither a generic Glass evening nor a full Wilson staging: the original ensemble’s accumulated performance knowledge, with Devlin translating the visual dimension. The caveat is substantial duration and repetition; one does not pop into Einstein after dinner in the usual sense.
