The Lake District's finest musical export British Sea Power brace themselves to perform at the Leeds and Reading festivals this weekend. The summer has seen the busy boys play for some of the country's finest minds - as they took on Oxbridge balls - and worked festival circuit gigs such as the Isle Of Wight, Glastonbury and T In the Park. Now the band, with a weakness for ornithology and Jamelia, step on stage at the Leeds Carling Festival on Friday and the Reading Carling Festival on Sunday.
