A concert review in the Chicago Tribune of this past week's Glass performance with Tim Fain at the Ravinia Festival. I don't understand what sort of venue the concert happened in. Glass and Fain do not use amplification in halls where it's not necessary. It's certainly not the composering "insisting on electronic sound enhancement" for a chamber music show.
Glass raised money for the Days & Nights Festival in Brooklyn a week and a half ago. He takes the show to San Francisco tonight. Here he talks about it in an extended interview with the SF Bay Guardian.
