Arista on Oct. 21 will release a Sarah McLachlan EP as a download, to be available for the first 30 days exclusively via Apple's iTunes Music Store, Billboard Bulletin reports.

"Acoustic Live EP 2003" has five cuts recorded in concert earlier this year: a pair from McLachlan's new album "Afterglow," due Nov. 4, and three older tracks.

"Fallen," the first single from "Afterglow," debuted in two versions last week on Billboard's Hot Digital Tracks chart, at No. 1 (album mix) and No. 4 (radio mix). The former logged 2,500 paid downloads, the largest one-week tally in the chart's three-month history. Both tracks were also 30-day iTunes exclusives.

As previously reported, McLachlan will perform Oct. 15 as part of New York radio station WLTW's One Night With Lite show at Madison Square Garden. Also set are appearances on "The Late Show With David Letterman" (Nov. 3), "The Tonight Show With Jay Leno" (Nov. 12) and "The Ellen DeGeneres Show" (Nov. 13).
