[3] Blasko's mother, Ellie (died c. 2000 of bowel cancer),[3][6][7] was a nurse and her father, Nikolai David Blaskow,[8] was a teacher at Gippsland Grammar School.

[2][5] By the age of 15, Blasko was concerned that she "wouldn't make it" and this was partially influenced by the church's apocalyptic message of the "End of the World" and "Christ's Return".

She eventually left the church in her final year of school, declaring that its emphasis on material success "just didn't fit" with her, or her interpretation of the scriptures.

[14] Both EP and single were produced by Hugh Wilson (King Luan, Vertigo, Science for Girls, Brooklyn Social, Huboi, The Blue Phoenix).

[1][21] She launched the EP at The Hopetoun Hotel, and by October the lead track, "Your Way", had been added to national radio station Triple J's play list.

[26] It was reviewed by Bernard Zuel of The Sydney Morning Herald, who felt "Blasko works in the territory where Ed Harcourt and Fiona Apple shine, taking some of the new acoustic framework (think Turin Brakes) and some of the folk-meets-electronica stuff that came out in the post-Portishead years and applies them to straightforward pop songs".

[17] Allmusic's Tammy La Gorce finds Blasko is "an entrancing artist who sings exceptionally well but is bent on making you guess what brews within her heart rather than pouring it out to you".

It is darker and more subdued than her debut, which sold to teens and adults and marked Blasko as an intriguing rising star; the second album is liberally spotted with regrets, plans for reconciliations and a quest to make sense of life".

[4] Susan Frances at AbsolutePunk.net rates the musicianship and production higher than Blasko's vocals, where "[she] is made up to sound more impressive than she actually is on the album ... [she has] a limited range so the tunes have a mundane drone.

Her vocal melodies transform the girl next door to a femme fatale figure which may explain why so many of those radiant reviews for her album come from male writers".

[33] Frances summarises the album as "pleasant and relates to people who are going through a loss or a low point in their lives ... tailored for those going through woeful moods".

[35] In October 2006 Blasko showcased tracks from her second album with an appearance at the Legs 11 concert, a breast cancer benefit, which included Tex Perkins and Tim Rogers playing with the Sydney Youth Orchestra.

[24][37] In 2008, Blasko co-composed the score, with Stefan Gregory (sound designer), for Bell Shakespeare's production of Hamlet, which ran from June to August.

[39] Whereas Helen Barry of Australian Stage felt Blasko was "truly sublime ... [h]er musical accompaniments add a layer of melancholy rapture to the performance which goes to the heart of Hamlet's grief, anger and loss.

[38] She had written all the tracks on her own – except "Over & Over",[41] which was co-written with David Byrne – without input from long term co-writer and co-producer, Cranny.

[47][48] Jason Treuen described the album for Rolling Stone as "a bold step in [her] journey as an artist and one that strips off the layers of her previous work to expose both her startling talent and her most naked emotions and fears".

[54] Nick Mason of The Dwarf website felt that although "[the live disc] showcases without doubt a faithful recreation of her latest work", it was "a fairly flimsy bonus to an album that can easily stand alone in its brilliance".

[54] During August 2010, Blasko recorded an album, Seeker Lover Keeper, in New York for the group of the same name with fellow founding members and Australian singer-songwriters, Sally Seltmann and Holly Throsby.

[26] To start recording tracks she had travelled first to Sweden earlier in the year and then in May went on to Sofia where she was backed by the Bulgarian Symphony Orchestra with strings arranged by Nicholas Wales.

[9] Beat Magazine's Chris Girdler noted "[it] has a completely different feel to [Seeker Lover Keeper] ... [and] is an insular, soul-searching piece that gets its balance from Blasko's gorgeous vocal guiding us through the trials and tribulations, as well as a sympathetic symphonic instrumentation".

[59] Craig Mathieson at The Age noted her last two albums were "starkly personal song cycles, staffed by jazz-inflected rhythms, sparsely exotic textures and a relentless sense of an artist getting to grips with her life.

[60] To promote the album, in February the next year, she toured every Australian state: where she invited the local capital city orchestra to accompany her on stage.

[64][65] In August 2015 Blasko announced that her fifth studio album, Eternal Return, was due for release in November with a preview in September–October at the Sydney Opera House.

[68] Much of Depth of Field was written and recorded during a two-week artist residency at Campbelltown Arts Centre in Sydney, Australia, alongside long time collaborator Nick Wales, David Hunt, and Ben Fletcher.

[72][73][74] She was initially hesitant to approach the comedy play, however upon reading it, "[she] realised that characters like Sebastian and Viola are experiencing a huge amount of grief" and that "the treatment of Malvolio" is "really intense".

[73] Travis Johnson of TimeOut praised Blasko's originals, "reminding us that, for all the ribaldry, the story is rooted in real emotion and longing".

In March 2005 she appeared at the South by Southwest festival where she wanted to "give some people who don't have a clue who you are, or those who have maybe heard a little about you, the chance to see what you do with their own eyes & ears.

[76] Blasko has toured the UK and Ireland with Tom McRae, and US and Canada with Ray LaMontagne, James Blunt and Martha Wainwright.

Blasko states that she "hopes to reimagine material from all of my albums and premiere some new songs as well", and that it "feels like the right time to challenge myself, take the leap and finally do some headline shows on my own".

[36] Blasko prefers vintage clothes, music, and art; in 2009 she revealed in a Rolling Stone Australia interview: "I like things that are old and have been lived in.
