This week's Mashup Monday serves up something even more meta than usual: The Downtown Fiction's frontman Cameron Leahy is not only serving up a musical contradiction in the form of his Alanis Morissette cover; the song he chose -- "Ironic" -- fits the series to a T, particularly because he puts an acoustic pop-rock spin on Alanis' upbeat, multi-instrumental original. And listen for an extra "ironic" lyric change about half-way through as Cameron sings about meeting the "girl of my dreams and meeting her beautiful wife."

"Growing up I used to listen to [Alanis' album] "Jagged Little Pill" all the time and I really respect her as a songwriter" the frontman says why he chose the Alanis hit, which climbed to No. 4 on the Hot 100 in 1996.

"I think everything about the song is hilarious," he says. "I think maybe deep down Alanis wrote the song knowing it was ironic she was writing a song called 'Ironic' that wasn't ironic."

A longtime Alanis fan, Leahy says he hopes his band, the Downtown Fiction, can take a page from her prowess as a songwriter, and possibly see some of the success she has. They are certainly off to a good start: the Fairfax, VA trio -- rounded out by drummer Eric Jones and bassist David Pavluk -- managed to get signed to Photo Finish Records only a year after forming in 2008. Last year the Downtown Fiction released debut EP, "Best I Never Had," and they are currently on tour through early April 2011 opening for The Ready Set."
