The Times also catches up with Greendale, Neil Young’s 2003 concept album, which is now being developed into many media formats, including a graphic novel drawn by Cliff Chiang.

That was just the beginning: Mr. Young went on to make “Greendale” into a concert tour, live recordings and an original film inspired by his post-9/11, save-the-Earth epic.

By now Mr. Young has moved on to new tours and releases and to activism against the war in Iraq. But “Greendale” continues to inspire spinoffs outside the music world, including a graphic novel and a multi-performer theater piece, which opens in New York on Wednesday.
