I've been to a billion concerts lately, it feels like, but I think the actual number is something closer to eight in the last ten days or something. I'll have to consult my calendar, which is almost indecipherable because of the last-minute crossings-out of concerts to attend something different. So there will be reports on Matthias Kaul, ICE, the Chicago Symphony playing Mahler 4 without a conductor, a newish trumpet concerto by H.K. Gruber, the latest Shulamit Ran premiere, and much, much more.
