Hosted by Angarsk in Siberia's Irkutsk Region, his marathon has been arranged to closely follow Guinness international project rules, complete with a monitoring team and two video cameras.
Temur had been playing non-stop for thirteen hours by 10 p.m., local time-5 p.m., Moscow time, says Elena Badyuk, marathon organiser.
"He looks quite cheerful and full of stamina, and there's inspiration in his music," she remarked to Novosti.
Though the rules envisage a five-minute break after every hour, the daring musician has taken only few. He is determined to play for twenty-five hours or even longer, if he can, to beat the previous Guinness Book record. It belongs to an Indian performer whose non-stop endeavour lasted twenty-four hours and a half.
Georgian national resident in Moscow, Temur was born in Tbilisi. He took up the guitar when a child of eleven. Last year's international contest in Los Angeles named him the world's best guitarist.
