Evanescence [ tickets ] is stretching out its late-2004 swing through North America as it continues to back its multi-platinum debut, "Fallen."

The group has added a number of late-November shows to its schedule, and has filled in some gaps in its December itinerary. Fellow rockers Seether [ tickets ], Finger Eleven [ tickets ] and Godhead [ tickets ] open on all dates.

Evanescence exploded onto the rock scene earlier this year with the March release of "Fallen," which debuted at No. 7 on The Billboard 200 album chart, and peaked at No. 3. Sales got off to a fast start thanks to the group's breakthrough hit, "Bring Me to Life," and have been buoyed by follow-up single "Going Under."

The group has lined up a non-album version of the "Fallen" cut "My Immortal" for its next single, according to the band's website.

"If you've seen Evanescence in concert on their most recent tour," reads a message posted on the site, "you've experience the incredible thrill when the whole band kicks into 'My Immortal' halfway into the song. Response to this arrangement was so strong that the band has produced a new version of 'My Immortal.'"

The updated version of the song is streaming at the group's site.

Now in its 33rd week on the chart, "Fallen"-which earlier this month was certified triple-platinum for shipping three million copies in the U.S.--sits at No. 22.

The album recently garnered the group an American Music Award nomination in the Favorite Album - Pop or Rock 'n Roll Music category. ABC-TV will air the award ceremony on Nov. 16.
