Late that year, she formed an indie rock trio, Seeker Lover Keeper, with fellow Australians Sarah Blasko and Holly Throsby.

[7] The band's six-track extended play, Double Happiness had "significant airplay" on national radio station, Triple J, where the group's music displayed "[s]himmering guitars and songs of young love".

[6][9] In 1996, for her 21st birthday she shared a party with fellow indie singer, Ben Lee (ex-Noise Addict), who turned 18 on the same day (11 September): each had a special cake made by Meyerratken with icing as a painting of each individual.

[10] Seltmann provided backing vocals on "Electricity" for Melbourne-based electronic band, The Avalanches' 1999 single – it was later on their debut album, Since I Left You (2000).

[13] By 2000, Sally Seltmann had re-invented her musical style to create New Buffalo: she adopted a sound that replaced guitars with keyboards over smooth paced bass and soothing beats.

[4][17] MusicOMH's Michael Hubbard noted "[it] is a slow-paced affair of 1950s sci-fi movie effects, cut-back rhythm section ... what we end up with is something that's not quite a soundtrack, not quite a pop tune and really not quite anything".

Largely composed of analogue organs, scratchy samples, and layers of Seltmann's thin-yet-tender voice, it's a profound piece of personal expression, a collection of lyrical pop-songs that're a product of a single individual".

When touring in support of the album, Seltmann sometimes performed solo and sometimes New Buffalo included other musicians, John Lee, Simon Parker and Brendan Webb.

Seltmann provided a cover version of Crowded House's "Four Seasons in One Day" for a tribute album, She Will Have Her Way (2005) – it was used in the 2011 promo of the Australian soap Neighbours.

[25] Also in August, Seltmann was invited by Deborah Conway to take part in the Broad Festival project, which toured major Australian cities including performing at the Sydney Opera House.

[14][32] By proxy, Seltmann's New Buffalo project became better known as she was mentioned in a number of publications, including Entertainment Weekly, which named her as an artist to watch in September 2007.

In December 2009, Sally Seltmann announced the details of her third studio album, Heart That's Pounding, which was released by Arts & Crafts on 6 April 2010.

[36] The lead single from the album, "Harmony to My Heartbeat", was released through iTunes on 24 November 2009,[37] and the accompanying music video directed by Antuong Nguyen of Moop Jaw followed on 15 December.

[40] Also that month she formed an indie rock trio, Seeker Lover Keeper, with fellow Australians Sarah Blasko and Holly Throsby.

Seltmann accompanied herself on a piano for her rendition of "Four Seasons in One Day", later Seeker Lover Keeper performed "Sinner" from Neil's 1998 album Try Whistling This.

[45] The Seltmanns had relocated to Los Angeles, after it was mostly written locally, she explained, "I wrote most of the songs for Hey Daydreamer in Sydney, but writing in LA feels GOOD!

[47] At the APRA Music Awards of 2016 Seltmann and Darren won Best Original Song Composed for the Screen for "Dancing in the Darkness", which was used in The Letdown on ABC-TV.

Set in 1995 in Sydney's Balmain, Lovesome tells the story of twenty one year old artist and waitress Joni Johnson, and her search for love.

[55][56] Luke also has a side career in pop rock; in 2007, he issued his debut album, Kiss That Lasted All Weekend, on Half A Cow Records.
