VIENNA, Va. (April 10, 2009)--Tom Rush says he's the biggest slacker in folk music, which may be why it took him 35 years to release his latest CD, "What I Know."

He blames a combination of "sloth," "inertia" and trouble landing a record deal for the delay.

Rush, 68, was touring most of those years except for the time he tried farming.

While Rush co-wrote seven of the 15 tracks on the album, he's primarily known for being an interpreter of other artists' music.

He was the first to record songs by Joni Mitchell, James Taylor and Jackson Browne.

Taylor has even credited Rush with his career, but Rush has never become as famous as those whose songs he sings.
