The superb organist Paul Jacobs won acclaim early on when in 2000, at 23, he played the complete organ works of Bach in a marathon to celebrate the 250th anniversary of the composer's death. On Saturday, Mr. Jacobs will be the curator when this feat is repeated, but collaboratively. Starting at 7 a.m. and running through Sunday at 1 a.m., Mr. Jacob and 19 other organists, all past or current students of his from the Juilliard School, will play Bach's complete organ works, about 150 pieces, on an instrument renowned as a Bach organ. The event is being presented by WQXR radio and will be live streamed on its website. Bach lovers can buy tickets for 75-minute slots, a half-day pass or, for the hearty, an all-day pass. Mr. Jacobs takes his turn for the 8 p.m. slot.
