Originally formed as Vertigo in 1996, they released the single "Forever Lately" in 1997 which became an Australian radio hit, followed by the single "Human Need". The Vertigo lineup consisted of lead singer Hugh Wilson as well as the three Leigh brothers, and they recorded an album: mixed by Chris Lord-Alge. Following the departure of their lead singer in 1999, Vertigo disbanded.
The three Leigh brothers, however, found vocalist Christian Argenti as their new lead singer and reformed with the slightly different name of Invertigo in 2000. The June 2000 single "Desensitised", which they performed on the variety show Russell Gilbert Live, signalled a return to the charts. A sample of "Desensitised" was featured on the Osmosis Jones Sampler CD. 2001 saw the release of another single, "Chances Are", in February 2001, and soon after, their debut album Forum in July. Since their only album, the band's current status is unknown. On the official Pseudo Echo site under the FAQ section it advises that Christian Argenti left the band in February 2003. Today, Christian is a radio announcer, having been the host of Melbourne sports radio station SEN's midnight to dawn program "All Night Appetitite", and is currently the presenter of "Talking Back The Night" on 92.5 Gold FM (Gold Coast) on the regional Southern Cross radio network.
