Play-throughs (with some a little yelling) of last week’s porch concert: Katerina Ruzickova’s Four Pieces for Piano, Lili Boulanger’s Trois Morceaux, Dorothy Rudd Moore’s A Little Whimsy, and Florence Price’s Silk Hat and Walking Cane. Plus a first play-through of Rachmaninov’s Prelude in G major, Op. 32 No. 5.
