A Stockhausen Moment is upon us: Southbank Centre is presenting a festival entitled Stockhausen: Cosmic Prophet, with the LICHT opera Donnerstag as its centerpiece, while the Holland Festival is preparing to unveil aus LICHT, a three-day condensation of the entire LICHT cycle (May 31-June 10).... The lineup for this year's Dog Star Orchestra series in and around Los Angeles (June 6-22) has been posted. It coincides with two other major new-music events in LA: the revival of Meredith Monk's ATLAS at the LA Phil (June 11-14) and the première of Anthony Davis's The Central Park Five at Long Beach Opera (June 15-23).... The New York Philharmonic's Music of Conscience festival (May 22-June 8) includes a revisiting of John Corigliano's First Symphony, his AIDS memorial, and David Lang's new Fidelio-inspired opera prisoner of the state.... As a prelude to the Philharmonia Orchestra's Weimar Berlin series, which begins on June 9, a nattily outfitted Gavin Plumley has put together an absorbing sequence of introductory videos. Esa-Pekka Salonen will bring much of this material to the LA Phil next season.... Sally Blackwood, Liza Lim, Peggy Polias and Bree van Reyk, all Australian-born composers, have written "Opera and the Doing of Women," a clarion call for gender equality in the opera sphere.
