Observations: Gonzales keeps on keeping on

"Being onstage is a physical challenge even for an hour" says pop musician Gonzales, who is setting his sights a little higher with a 27-hour performance marathon, starting tomorrow. The Canadian star is known not only for his own excellent Solo Piano album, but also for his collaboration with Peaches and his work as the producer behind Feist's award-winning albums. Taking a break from his current work in the studio with thecocknbullkid, Gonzales is now aiming to break the Guinness World Record for the longest concert by a solo artist, currently held by Prasanna Gudi in India for his 26 hours and 12 minutes sitar recital in December.

"I will do this to push my musical and physical stamina", said Gonzales, explaining his motivation. "I believe music is part art, part athletics and this 27-hour concert will demonstrate both aspects."

He is allowed just five minutes' rest per hour and will be watched over by an official Guinness Book of World Records adjudicator. He also has to pass a drugs test.

Starting tomorrow at 11pm and continuing throughout Sunday, the concert at the Cine 13 Theatre in Montmartre in Paris will feature around 300 familiar songs from all eras and styles of music.

But Gonzales won't repeat any of the material. "I aim to break the record without sounding like a broken record" he assured.
