[3] They recorded 12 tracks at the ABC studios in December, which "received national airplay": they followed with an Australian tour including an impromptu appearance at the Adelaide Fringe Festival.

[3] Mike Jackson of The Canberra Times caught their gig at a local venue, Tilley Devine's Cafe Gallery, in April 1990, and observed that their music, "is full of lovely harmonies and a selection of songs that places them somewhere between The Flying Pickets and Sydney women's a'capella group Blindman's Holiday.

Their debut self-titled album appeared in 1999, which was "recorded, mixed and mastered" by Ross Cockle (Mother Goose, Australian Crawl, Beargarden) with the line-up of Shanahan, Diana Clark, Vicki King and Andrea Watson.

[12] Their second album, World Citizen (March 2002), had Shanahan and King joined by Heidi Bradburn and Mihi Rangi; it was co-produced by the group with Siiri Metsar via Black Market Music .

[13] Dieter Bajzek of Folk Alliance Australia observed, "Finally a full-length, well recorded and mastered CD... from this polished and hard-working female a cappella quartet, supported by tasteful percussion.

[17] As of February 2005, Akasa had continued with the line-up of Bradburn, Clark, King and Watson: they finished their set list with "Shanahan's 'Walk with Me' [which] radiated a serene, hymn-like quality that made them especially poignant.

Shanahan was one of the founding members of Akasa, and [the song] served not only as a heartfelt conclusion to the concert, but a fitting tribute to a woman who embodied so many of the qualities that still resonate in the group's music.".
