If you haven't made it to the Aspen Music Festival's Benedict Music Tent yet this summer, plan to do so in the next few days, because the summer season ends on Sunday afternoon. The venerable festival is offering a packed schedule for the final four days - the Aspen Opera Theater Center is performing Mozart's Cosi fan tutte at the Wheeler Opera House, pianist Conrad Tao and violinist Stefan Jackiw perform with the Aspen Chamber Symphony on Friday evening and there will be two recitals in Harris Hall on Saturday. Sunday's concert includes soprano soloist Suzanna Phillips and Mahler's splendid Symphony No. 6 to close out the season. More at www.aspenmusicfestival.com.
