Prom 48: Classical Tectonics

The Iceland Symphony Orchestra makes its Proms debut with works by two homegrown composers, both inspired by Iceland’s geology. The slow-growing, primal force of Leifs’s Geysir is balanced by the shifting tectonics of Tómasson’s Magma. Jonathan Biss joins the orchestra for Schumann’s Piano Concerto, and the concert closes with Beethoven’s dramatic Fifth Symphony.
