This year’s spring Junior/Senior Concert by Musicians Emergency Fund (MEF) will be Franz Liszt: Holy and Infernal Genius, with all-star pianists Adam Golka and Orion Weiss joined by the brilliant young Canadian-American mezzo-soprano Lauren Eberwein.  Their program honors the multifaceted genius of Hungary’s legendary virtuoso pianist/composer with a selection of his works for solo piano, even for two pianos, plus selections in German, Italian and French from his rich, relatively less familiar body of songs.
