Yuja, live from New York. Pianist Yuja Wang has worked up a solo recital she's playing in the United States, Paris, and Germany, and at the Concertgebouw, but listeners all over can hear the program when she brings it to Carnegie Hall at 8 p.m. Saturday. Repertoire includes Brahms' Ballades, Op. 10, Nos. 1 and 2; Schumann's Kreisleriana, Op. 16; and the Beethoven Piano Sonata No. 29 in B-flat Major, Op. 106, "Hammerklavier." The Curtis Institute of Music graduate is something of a visual phenomenon for many, and for those fans, the Carnegie Hall recital will be streamed live online, and available for viewing on free replay for 90 days, at medici.tv.

The hum of the earth . . . Piffaro, the Philadelphia Renaissance band, is heading deep into 16th-century esoterica with Harmony of the Spheres, a program Saturday. The concept dates to Pythagoras, who theorized that music can replicate the hum of the planets, the proof on this program coming from composers such as Josquin, Isaac, Facino, Galilei, and Zarlino. The multimedia performances feature Les Canards Chantants, the exciting early-music vocal group recently transplanted to Philadelphia. Neither venue nor performance times are typical: 2 and 7 p.m. Saturday at the Conwell Dance Theater at Temple University. Information: www.piffaro.org.
