Classical picks: Curtis highlights online; Ocean Grove organ concert

Curtis encores. The main classical season may be over, but you can revisit some high points from recent performances at the Curtis Institute of Music via videos on the school's website. Captured is a nicely developing interpretation by Bolai Cao of the Brahms Piano Sonata No. 1 in C Major, a Mahler Symphony No. 5 conducted by Jahja Ling, a Mendelssohn quartet, Gershwin and Strauss vocal works, as well as new music. When you've had enough of organized sound, click on a performance by a cellist and pianist of Cage's 4'33." Strangely, the performance lasts a bit more than five minutes. These are students, after all, and maybe it just takes them longer to get through all those notes. curtisperforms.curtis.edu.

Organ fest in a time warp. Ocean Grove's Great Auditorium, often described as Noah's ark turned upside down, is where Joseph Jongen's rarely heard Symphonie Concertante, originally written for Philadelphia's Wanamaker Organ, will be performed at 7:30 p.m. Thursday by Gordon Turk on the auditorium's grander-than-grand pipe organ. The MidAtlantic Opera Orchestra under Jason Tramm also features opera arias by Margaret Mezzacappa, who has many local admirers from her years at the Academy of Vocal Arts. 54 Pilgrim Pathway, Ocean Grove, N.J. Tickets: $16. Information: 800-590-4064 and www.oceangrove.org.
