2009

Notable artists such as Rolo Tomassi, Just Jack, Toddla T, Pixie Lott, Little Boots, Example, The Eighties Matchbox B-Line Disaster, The XX and Reverend and The Makers, who headlined, played at the festival. The festival was a huge success,^[5] attracting 35,000 fans.^[6] The organizers, as well as councillors and Sheffielders, praised the festival. The festivals popularity, along with positive reviews, led to the 2010 event being announced. The festival-goers had to queue to get wristbands, which gave them access to the different stages.

2009's festival recycled 400 litres of paper, 2080 litres of plastic and 560 litres of aluminium in the outdoor venues alone.^[7] This led to an environmental campaign in 2010 in which the festival seeks to reduce its environmental impact.
