No self-respecting 'World' Music festival or magazine would promote a UK 'pop' group but would and do promote groups who may be the most popular 'pop' group in their country. This is a form of reverse snobbery that benefits no music making.

I would like to see the bigger festivals like Glastonbury - who have different stages for different styles - mix them up a bit.

With special festivals or special stages you tend to see act after act who are all from different parts of the world and who may be very talented but who, when they are singing words that you cannot understand, tend to limit the excitement and lessen the effect of the new.

I suggest the best way to promote good acts like these would be to put them on the main festival stage sandwiched between the two (currently) biggest conventional acts.
