Greek-Australian singer and songwriter VASSY has released “Dirty Martini,” a collaboration with Sydney producer Oscar Jamo that follows four consecutive weeks at the top of Australia’s ARIA Club Tracks chart with her earlier single “Day N Night.”
Released Friday, November 13, through KMVMUSIC, the new track is already listed as a new entry at No. 14 on the ARIA Club Tracks chart dated November 16. It brings together two artists whose working relationship began when Jamo remixed “Day N Night,” VASSY’s collaboration with fellow Australian producer Bust-R.
In a press release, VASSY’s team describes “Dirty Martini” as a darker club track built around her vocals and Jamo’s production. The project continues a series of collaborations linking the US-based artist with producers from her home country.
Jamo’s contribution to the “Day N Night” remix package provided the starting point for the partnership, according to the release. His name appears among the remix credits on ARIA’s listings for the song, alongside Mark Maxwell, St. Croix, Kue and Jeff Straw.
Four weeks at No. 1 for “Day N Night”
“Day N Night” held the top position on the ARIA charts dated August 31, September 7, September 14 and September 21. The run came after VASSY’s return to Tomorrowland to introduce the song with Bust-R, bringing the collaboration to the Belgian electronic music festival’s audience.
The festival carried a personal connection for VASSY, who had previously performed “Secrets” there with Tiësto. Announcing her return earlier this year, she described Tomorrowland as a turning point in her career.
Her 2026 releases have also attracted support in Britain. “On Me,” recorded with Australian producer Mind Electric, reached No. 1 on the UK Commercial Pop Top 30, according to Australian music publication The Music.
Vassy: From Darwin to an international dance career
Born Vasiliki Karagiorgos in Darwin to Greek immigrant parents, VASSY later moved to Los Angeles to pursue her music career. Her international collaborations include “Bad” with David Guetta and Showtek and “Secrets” with Tiësto and KSHMR.
“Bad” earned Billions List recognition from APRA AMCOS, the Australian music rights organization. It admitted the song to its billion-stream list in 2020, counting plays across major services including Spotify, Apple Music and YouTube.
VASSY also became the first woman to receive the Electronic Dance Music Awards’ Icon Award in 2023. Speaking to Greek Reporter at the time, she recalled coming from “a humble, hard working Greek family” and pursuing a career in a genre dominated by DJs.
Her recent projects have explored music beyond dance floors. The 2024 album “Supreme” drew on her earlier musical influences, while the 2025 “BossAcoustics” EP revisited her jazz and bossa nova roots.
Discussing that EP with Greek Reporter, she recalled the Greek music her mother played while she was growing up. She described the project as a “return to the music that first made me fall in love with singing.”
“Dirty Martini” is available on streaming platforms through KMVMUSIC.
