Following a wave of negative reviews, ZZ Top guitarist Billy Gibbons has abruptly cancelled his Australian tour early.

In a short statement posted to Facebook this morning, the tour promoter confirmed that Gibbons' last date in Brisbane has been cancelled due to "unexpected circumstances".

Fans labelled Gibbons shows in New South Wales this past weekend as a "rip off"  and a "disaster" with some demanding refunds.

It was reported that the 68-year-old performed just three and four songs respectively at shows last Friday and Saturday, while others claimed he appeared disinterested while on stage.

The Music has reached out to promoters for further comment.
