Iconic Brisbane band Powderfinger has treated festival-goers at Splendour in the Grass in Byron Bay to a surprise set.

Frontman Bernard Fanning was set to play solo on Saturday night, but was instead joined by bandmates Darren Middleton, Ian Haug and John Collins — in their first performance together in seven years.

"It's been 10 years since Powderfinger played at Splendour, so let's have a little anniversary party," Fanning told the crowd.

The brief once-off set delighted a crowd of around 10,000, with the band playing classics including (Baby I Got You) On My Mind and These Days.

Music lovers took to social media, sharing photos and videos of the gig.
