So...
I ended up going to my friend's Art Song Jam last night, and it turned out to be quite a nice evening of music-making. Most of the singers were people she had worked with before, but there were also some friends of friends, as well as two "celebrities": Cori Ellison (the former dramaturg with City Opera and one of the early proponents of "Met Titles" at The Met), and WQXR's Naomi Lewin. There was some Brahms, some Debussy, some Ricky Ian Gordon, some Berg(!), some Duparc...
During the middle of Ravel's "Kaddish", my friend, Jennifer, stopped playing the piano, turned to look at me... "Do you know this piece? I keep missing the clef changes." -Well... It's been about 25 years since I've played it... "Why don't you finish playing it then?" ...Um... OK. So I did. Excited and scared.
