It seemed odd on paper. Two Mahler symphonies? In one night? I don't think I'd ever seen that. Last night's Prom showed why not. While Valery Gergiev's second half Mahler Five saw the stage transfigured into a writhing sea of bodies and the air filled with an epic sound, his first half starter, Mahler Four, fell flat on its face. One was a performance; the other was a rehearsal to a performance.
