Title: Glade Festival
Content:  The 2008 event, held during 18–20 July, underwent some consolidation in the light of "festival fatigue" in the UK festivals market as a whole, caused by a combination of poor weather in the previous year, cheaper festivals in continental Europe and too many UK festivals chasing fewer customers during a period of economic downturn. This consolidation took the form of a reduction in capacity from 18,000 to 12,000 and the loss of some of the additional venues that were added to the 2007 event – namely the Roots Stage, the Algorithm arts space and the Nectar arts/talks space. Some of the art has been moved to others spaces, such as the inSpiral (formerly ID Spiral) chill-out space. However, the organisers stressed that no advertised performers were cut from any line-ups, nor were there any plans to do so. Despite this, Glade went on to win 'Best Dance Music Festival' at the 2008 UK Festival awards.
