Just to give you an idea how the other fraction lives, here's what the Munich Philharmonic performed in May: Something called _Implosion_ by someone called Joerg Widman; _Areal_, a "landscape" for piano and orchestra (world premiere)by Christoph Staude; _Black Penininsulas_ for orchestra and tape by York Hoeller, all these conducted by one George Schmoehe. New program: _Pohjolas' Daughter_ by Sibelius; 8th Symphony by Einojuhani Rautavaara; First Piano Concerto, Brahms, Radu Luou, conductor for these, Osmo Vanska. Once a month I simply have to go, so having skipped the above two programs what I got to experience last night was: _Dithyrambe_, concerto for quartet (Arditti) and orchestra, by Wolfgang Rihm; and 9th Symphony, Mahler, conductor Lothar Zagrosek. I'd experienced Rihm before in a festival at Lucerne that focused on his work. Last night was as puzlling as Lucerne had been. The piece is a 35-minute rumble--, think a bubbling musical cauldron-- that geyser-like, from time to time, spews forth a chordal surge that blasts across the orchestra and ends, perhaps, in the twang of two harps. Or, mayalsobe, with the resonant klunk of some wooden percussive thingie,. The noise goes on and on with about as much accentuation to it asspoken French language. And, like it, it' s pointed up, now and then, by a rise in volume, or a sputter, or a shriek, or a tintinabulation,or a percussive BOP. For all this the forces and conductor Zagrosek were rewarded by three curtain calls and quite a lot of booing. Poor Zagrosek, a poppinjay gymnast of a conductor, deserved neither: he just beat time. But he did indicate that he knew the score by showing impressive agitation before some high point, such as it was, in the score. Trouble was, the piece he had been conducting clearly needed firm and canny management to make those swoops, and POPS, and sweeps work. Last night they sadly did not--at least not for me. His Mahler 9 was better--yet with a second movement and final movement of such splendor he couldn't really miss.The accomplishment did,however, take him 105 minutes. Denis Fodor
