Was trying to think of something to send Travis for his tumblr playlist and remembered this home cassette taping of Margaret Leng Tan performing Philip Glass' "Modern Love Waltz" on toy pianos. This led to looking for other versions of the song, which might also affectionately be called the "OCD Tango." Found two on YouTube, which are not as good Leng Tan's.
Leng Tan adapted the tune for two toy pianos, played with brittle relentlessness. The YouTubes are conservatory-ish piano solos, played with attempts at expression and emotion. Wrong, wrong. Of the two, Amy Briggs' is better for being more robotic. Branka Parlic's version recalls Liberace, only boring.
