Tuning Up. The Philadelphia Singers are gone, but a successor choir of sorts aims to appear this fall. The Philadelphia Choral Collective plans a three-concert season - at Christmas with a 24-voice chamber choir, around Valentine's Day with select choir members and a jazz trio in American Songbook repertoire, and in the spring with both the chamber choir and full symphonic choir. One round of auditions has been held, and another is planned for late August, says artistic director Brian Schkeeper. Audition information: - Peter Dobrin

Tales from Carnegie Hall. Remember that great concert your heard at Carnegie Hall? Do share. Carnegie is collecting personal stories online in celebration of its 125th anniversary. Dozens of charming vignettes are published already - memories of performances by Toscanini and Bernstein, of course, but also of Vietnam War protests, the awe of schoolchildren singing there for the first time, and, as expressed by pianist Jonathan Biss, what it feels like to take that long walk to the keyboard at center stage. - P.D.

Under Stalin's Shadow . . . was basically the story of Dmitri Shostakovich's artistically repressed life, but it is also the title of the new series of recordings by the Boston Symphony Orchestra under its new music director, Andris Nelsons. Philadelphians have been enviously regarding the Deutsche Grammophon contract that came with it. With the orchestra's trademark string sound and hall ambience, Boston certainly deserves it. The performance of the Shostakovich Symphony No. 10 seems unduly genteel at first but speaks with a sure inner force. The disc begins with crashing dissonances from the opera Lady Macbeth of Mtsensk, suggesting why Stalin initially became so upset with Shostakovich. - David Patrick Stearns
