The four-man vocal ensemble New York Polyphony sings ancient music built for big resonant spaces. Since they can't just pop into St. Patrick's Cathedral any time they need to practice a renaissance mass, the group rehearses sometimes in the Jackson Heights home of bass singer Craig Phillips. There, in a modest-sized living room, they can hear every detail. "It's a very different experience rehearsing in a dry room and a small room," says tenor Geoffrey Silver. "You actually hear what you and your colleagues are singing, there's no watercolor wash over what you are doing."

It's tough to concentrate on the rigors of Beethoven with jackhammers pounding in your ears. So when they started demolishing the building next to Jonathan Biss, he moved his piano out of his apartment into a separate studio, away from the commotion. "I would get up in the morning, the piano wasn't there, and I had to leave my apartment to go practice and I've decided that's a much more productive way of working," he says. Biss needs a good working environment for his massive project.

Jeremy Denk has his own personal "piano boot camp." Actually, it's his cramped Manhattan apartment. Beside his beloved books, a trusty coffee pot and a laptop, there's not much to do except practice. Which Denk does, hours and hours a day on a Steinway wedged into his living room. On a good day, he brews pot of coffee number one at about 11, then plays for about five hours. Perhaps a run to the gym, then pot number two is brewed at about 6, followed by more playing — until the neighbors complain.

Back in March, former All Songs intern Dan Raby used this space to sing the praises of Montreal singer-songwriter JBM, a.k.a. Jesse B. Marchant, whose deliberately paced folk-pop hangs on the lingering empty spaces between notes.
