[2] While still a member of Kevin Borich Express, Balbi had guested on bass guitar for fellow Sydney-based band, the Change's single, "Forever Young", alongside that group's Stuart Fraser on lead guitar (ex-Feather, Smith), Kevin Nicol on drums (ex-Dial X) and Jon Stevens on lead vocals.

[2][3] Early in 1986 the pub rockers, Noiseworks, were formed in Sydney with the line-up of Balbi on bass guitar and backing vocals, Justin Stanley on keyboards with the Change's Fraser, Nicol and Stevens.

[2][3] Stanley explained to Simon Moy of The Canberra Times how the group had formed "[Balbi and I] heard [Stevens], [Fraser] and [Nicol] were doing a little writing and playing around so we just got together one day down at the pub, got pissed and got on and that's how it went.

[2][3] In 1993 Balbi and Stanley formed a psychedelic pop group and production duo, Electric Hippies, which issued their debut extended play, It's Cool, in October of that year.

[8] It included the track, "Jonny Courageous"; according to Australian musicologist, Ian McFarlane, it "was reputedly a swipe at former Noiseworks frontman Jon Stevens.

[10] McFarlane opined that it "mixed Revolver-era Beatles melodies with a Ziggy Stardust-period David Bowie glam rock aesthetic.

[11] Balbi, on lead vocals, formed a new group, Universe, in 1997 which consisted of Jim Denley on flute, Cathy Green on bass guitar (ex-X), Matt McCormack a.k.a.

[8] Balbi, Green and McCormack were joined by Angus Diggs on drums and Ilan Kidron on flute for their single, "Be My Gun" (October 1998), and the related album, Present.

[citation needed] In October 2009, Balbi, released his solo single "I Found You", out on UK label Foundry Records.
