When the deal came to an abrupt end six months later due to Tom Whalley leaving to Warners the band played their last few shows in Nashville and moved to London, United Kingdom to seek new avenues.

She co-produced and co-engineered it with Robin Eaton, Ron Fair, and Brad Jones at Alex the Great Studios in Nashville, Tennessee.

[4][20] AllMusic's Robert L. Doerschuk described Flutterby as "[a] low-key tour de force, [it] reflects an uncommon maturity and breadth of talent, particularly for a debut effort.

Boucher commands all the essential instruments; more than that, she layers her parts with an ear toward sounding like a solid backup band, as opposed to showing off.

She also performs and records bass guitar and vocals as part of Elle Macho, a Nashville-based trio she formed with guitarist David Mead and drummer Lindsay Jamieson.

Unlike the original, which she recorded on her own, the remake enlisted help from other musicians, including Sarah McLachlan, Sara Bareilles, Katie Herzig.

[29] Butterfly Boucher recorded a version of David Bowie's song "Changes", on the Shrek 2: Motion Picture Soundtrack, released in May 2004, for the film of the same name.
