The former eighth-season finalist will release his new album "Heartstrings" on March 11 and will also return to the American Idol stage that night to perform during the live results' show broadcast that will reveal the ninth season's Top 12.
The broadcast will feature MacIntyre and fellow former eighth-season finalist Matt Giraud delivering their dueling piano performance that was popular during American Idol's Summer 2008 tour.
"It was talked about for last year's finale. And I was disappointed when it didn't happen" MacIntyre toldThe Los Angeles Times in a Thursday report.
"But [executive producer] Ken Warwick always said he wanted to bring it back, so we've been in touch about it. I'm really excited. It's one of my favorite Billy Joel songs, and it allows me and Matt to banter back and forth as if we're trying to show each other up."
While "Heartstrings" represents MacIntyre's first post-American Idol album, it's actually his seventh independently released full-length studio album.
