This week in Philly music: Italy, north and south

Tempesta di Mare likes to build concerts around scholarly themes, but there’s nothing academic about the music itself. For their next concert, some of the first chairs in the Tempesta di Mare Baroque Orchestra will play chamber music from the northern and southern capitals of Italian Baroque music, Venice and Naples. The instruments will be, as usual, 18th-century versions of the recorder, the lute, the violin, the cello, and the harpsichord. The music will include established Baroque favorites and the discoveries Tempesta’s music directors pull from the shelves and databases that store the huge library Baroque composers left us.

Tempesta di Mare will present “A Tale of Two Italian Cities” on Saturday, April 23, at 8pm at Arch Street Meeting House, 320 Arch Street and on Sunday, April 24, at 4pm at Presbyterian Church of Chestnut Hill, 8855 Germantown Avenue. “Preferred” tickets are $34; general admission $24. Full-time students and youth (grades 3-12) free at the door. Tickets are available online and at the door.
