Flanagan has released several albums and has toured Australia with her music and as a part of festival ensembles. She has collaborated with
Sinéad O'Connor,
Meshell Ndegeocello, poet
Sam Wagan Watson,
The Black Arm Band,
Paul Kelly and
Ursula Yovich, and recorded a duet with
Marlon Williams of
Archie Roach’s "I’ve Lied". Flanagan was invited by
Deborah Conway to be part of her Song Trails project for the 2009 and 2011
Queensland Music Festivals, which led to her collaborating with Australian artists Peter Farnan (
Boom Crash Opera),
Robert Forster (
The Go-Betweens) and
Rebecca Barnard (
Rebecca's Empire) to deliver a series of workshops and to perform concerts across regional
Queensland. Flanagan composed a show entitled
Midnight Muses, based on the work of Brisbane poet
Samuel Wagan Watson, for the
Adelaide Cabaret Festival in 2011. It later appeared at the 2013
Sydney Festival. She was invited to perform as a featured soloist in the first Australian production of Leonard Bernstein's
MASS at the 2012
Adelaide Festival. In late 2015 Flanagan was invited by
Archie Roach to record a duet of his song "I've Lied" with Marlon Williams for the 25th Anniversary release of
Charcoal Lane.
Rolling Stone Australia gave the anniversary album four-and-a-half stars. ==Arts administration==
