The third annual Festival of Slow Music is coming to an end, but it is being serenaded off in style with a constant stream of deep melodies from The Lost Ones Gallery on Camp Street.

Nine acclaimed pianists began  proceedings at 12pm on Saturday, with a rotating shift system ensuring the music doesn’t stop until 12pm on Sunday.

The Lost Ones Gallery co-founder Stephen Pigott described the experience as different to the standard gallery exhibit.

“It's a bit of an experiment, but it's no doubt a fun one,” Mr Pigott said, adding that the real interest lies in who will turn up in the early hours of Sunday morning.

“I'm not sure how it will go at 2pm or 3pm,” he laughed.

“(But) people are interested in it and they're turning up.

“It's quite relaxed, the fires are on and it's comfortable.”

Included in the line-up are renowned pianists Michael Kieran Harvey and Tony Gould.

Now in its third year and running from August 22-30, the festival reflects the philosophy of the slow food movement but with a focus on the sensation of hearing.

The main weekend includes more than 20 concerts featuring local, national and international acts.​
