Russell has described his Indoor Garden Party shows as “an event, a band, a happening.”

‘It’s liquid. The staff changes, but it’s always great. It’s like a festival where I bring together people I admire, musicians and storytellers, and we put on a show,” he said.

Despite his successful acting career, Russell has always had an interest in singing.

In the eighties he recorded the song I Want to Be Like Marlon Brando under the name Russ le Roq.

He soon became the lead singer of the band 30 Odd Foot of Grunts.
