His first job, at age fifteen, was working for the local stately home Knebworth House which in the mid-seventies became the biggest venue in the United Kingdom for outdoor shows and hosted bands such as Led Zeppelin, The Rolling Stones and Pink Floyd.

Whilst critically acclaimed, the resultant financial losses led to Gabriel playing a reformed Genesis Concert and Elbourne relocating to London.

He managed various bands including Green on Red, David Rudder,[12] and Gaye Bykers on Acid, and gradually became more involved with the Glastonbury Festival,[13] ending up as its main booker.

[14] Sébastien Nasra collaborated with Elbourne and, in 2006, co-founded M for Montreal, a platform for showcasing local musicians and helping them expand their international networks.

The project aimed "to create collaboration and unified action for a healthy, more sustainable music scene" in South Australia.
