The solo performer aims to get people moving with his ‘big sounding one-man band’.
Ash spoke to the Times from his base in Ocean Shores, New South Wales.
He said the riverfront setting at Ravenswood suited the style of his performance.
‘I’ll be playing a smattering of songs from my seven studio albums,’ he said.
‘I started organically such as doing percussion with my feet, but then my music featured more electronic sounds.
‘My show at Ravenswood will return to when I was experimenting with different sounds.’
Grunwald’s first album Introducing relied heavily on traditional blues. His next album I Don’t Believe was released in 2004 and it grafted technology into the Delta swamp genre.
Grunwald has opened for acts such as Keith Urban, Jack Johnson and Missy Higgins.
His style is a unique blend of roots, blues, beats and a lot of groove.
