Felix Mendelssohn first got the idea for hisThird Symphony while on a trip to Scotland. He was 20 years old at the time, but he wasn’t in any hurry to finish the symphony: it took him 13 years to complete the work. Mendelssohn’s Third Symphony - the Scottish Symphony - is our Evening Masterwork tonight at 7 on Classical WSMR 89.1 and 103.9.
