Interested in some classical music on a Friday? Tune into the free live broadcast of the Detroit Symphony Orchestra (thanks to @benforta for the tip).
Symphony No. 4 in F minor, was written between 1877 and 1878 and was first performed in Moscow on February 22, 1878, with Nikolai Rubinstein as conductor. [via dso.org]
Live broadcasts of classical concerts have become increasingly popular in recent years, providing an excellent distribution alternative to broadcast, which is dominated by main stream music.
