Zidane soundtrack - tickets still available

https://www.quaytickets.com/mif/, the official ticket seller for Manchester International Festival, still has approx 30 tickets per night for Mogwai's first live performances of the Zidane OST in Manchester (19th and 20th July 2013). If these shows are accesible to you and you haven't booked - why?? How can it be anything less than amazing?
