As Ron and I were toiling up the many steps of Angel’s Flight today to get to California Plaza for lunch, I heard the strains of “Beat It” floating out above us. At first, I thought someone was playing the melody on a squealing 80s electric guitar. Ron thought the sound resembled the electric fiddle of Riverdance. When we got to the top of the stairs, we saw a woman playing a haegum, a traditional Koean two-stringed upright fiddle, as part of the Grand Performances series. I was baffled, but impressed. I love getting surprises like this when I leave the office. As we settled down at one of the tables with sandwiches from my new favorite place Mendocino Farms, HaegumPlus tore through flamenco, Klezmer and jazz. When Kang Eun Il, the leader of the ensemble, introduced herself, she spoke in Korean. But clearly, she’s fluent in a lot of different musical languages.
