When his rock band ran afoul of the Soviet authorities, classically-trained Latvian composer Imants Kalniņš turned to writing symphonies. His Symphony No. 4 was his eloquent response, as much indebted to illegal rock groups of the West as it was to Latvian folklore. Hear Kalniņš stick it to the man this afternoon, on his 76th birthday. We’ll also have a Piano Concerto by Keith Emerson, of the progressive rock group Emerson, Lake & Palmer, among our featured works, from 4 to 6 p.m. EDT.

Then, immediately following, stick around for music of Jerry Goldsmith on “Picture Perfect,” on WWFM – The Classical Network and wwfm.org.
