Marc is a central character in Perri Knize’s new book Grand Obsession: A Piano Odyssey, to published by Scribner in January 2008. He is the technician who created the piano voice that Knize falls in love with and is haunted by when she plays a Grotrian grand Marc prepared for Beethoven Pianos in New York, and he becomes her guide throughout her “odyssey.”

“At the touch of the keys, I am swept away by powerful waves of sound,” the author writes of playing a piano voiced by Marc Wienert. “The treble is bell-like and sparkling, full of color, shimmering northern lights. The middle section is smoky and mysterious, as if rising from the larynx of a great contralto. A soul seems to reside in the belly of this piano, and it reaches out to touch mine, igniting a spark of desire that quickly catches fire.”

Piano is Key to Brown’s Studio
, by Christopher Walsh

There are few experiences more pleasing than to sit at an ornately carved 1881 Steinway D Centennial concert grand piano as its unimaginably honeyed tones fill the room. Add a brilliant, sunlit view of the Hudson River, and you may just transcend to the astral plane.

“The piano is extremely special,” agrees Louis Brown, principal of L. Brown Recording, located in New York’s historic Film Center Building. “They only made around 400 of these, between 1876 and 1884, for the centennial of the United States. Doing classical music, I have to have something unique, and a Steinway D was a must.”

The Steinway was rebuilt and is maintained weekly by Marc Wienert of Action Direct Piano. “To capture classical music,” says Brown, “it’s very important that it’s tuned and voiced to perfection, and Marc cares for this piano meticulously.”
