Symphomania, Will Robin's twenty-four-hour festival of twenty-first-century orchestral music, is under way on Q2. The discovery of the morning has been Georges Lentz's gorgeously hellish Jerusalem (after Blake), a pick by the ever-inquisitive David Robertson.... I'm looking forward to hearing John Adams's latest big piece, Scheherezade.2, at the New York Philharmonic this week. It's billed as a "dramatic symphony for violin and orchestra."... Another beguiling musical fiction from the fertile mind of Jennifer Walshe: Historical Documents of the Irish Avant-Garde. More here.... The first installment of Lisa Bielawa's online opera Vireo, subtitled "the spiritual biography of a witch's accuser," will appear on March 31.... Heartiest congratulations to Zachary Woolfe, who, after several years of incisive free-lance criticism for the New York Times, has been hired as the paper's new classical-music editor. This is the first classical hire by the Times since Tony Tommasini joined the staff in the late nineties.... Tim Rutherford-Johnson listens to the scary, brilliant music of Adam de la Cour.... Steve Smith, whose blog is springing back to life, listens to Pierluigi Billone.... Also in the Globe: Jeremy Eichler on Feldman and Rothko. An outstanding recent Feldman release is the Flux Quartet's rendition of the First Quartet, Structures, and Three Pieces, on Mode.
