I was unfamiliar with San Francisco’s Cascada de Flores until their album Radio Flor (Ita Music, 2013) reached me. I’m now notably better off than I was, because their sound is a warm and wonderful mix of Cuban and Mexican roots played by an acoustic lineup of guitars, bass, piano, percussion and trumpet topped off by the silken spice of vocals by Arwen Lawrence. It’s a vintage-sounding affair, leisurely paced and completely enchanting. Sure, you may think you don’t want to hear Rodgers and Hart’s “With a Song in My Heart” done as a seven-minute danzon, but trust me, you do. I’ll say no more about this music; you simply must experience it for yourself.
