The inaugural South Asian Literature Festival takes place in London over 10 days. It has drawn authors such as Amit Chaudhuri, Fatima Bhutto, Kenan Malik and Mohamed Hanif, as well as publishers, translators and artists (performance and graphic) connected with the region. Over and above events relating to tribal art, oral culture, travel writing, cultural offence and the literary divide (if such there be) between India and Pakistan, the festival will also feature the announcement of the shortlist for the inaugural DSC Prize for South Asian Literature, a $50,000 award recognising "writers of any ethnicity writing about South Asia and its diasporas", the winner of which will be declared at the Jaipur Literature Festival in January. Theartsdesk speaks to prize-winning Sri Lankan author Romesh Gunesekera, about the festival’s ambitions and the rude health of subcontinent literature.

Amazingly, the Vale of Glamorgan Festival has been on the go for more than 40 years, and has got better and better as it has gone along. Until recently, any kind of mould-breaking musical enterprise was likely to collide with the entrenched interests of the Taffia, the Cardiff and County Club, the Welsh Arts Council and the Land of Song.

The group Pingasan’k “calls for good spirits”. The name refers to “a bucket to put rice in, tied with the bark of a tree”. Regardless of rice or spirits, this band touched my heart. The gentle, haunting sounds come from the bamboo tube zithers (pratuon’k) made from giant mountain bamboo, which is only cut down when they see the moon. “We do not want our instrument to smell sweet or our insects will bite it,” explains leader Arthur Kanying.

The world music scene is hungry for new sensations - and Omar Souleyman, about to hit London and the Shambhala Festival, well deserves to be one of them. In the early 1980s the hunger for the exotic focused on anything that came from the parallel universes untouched by the pressures of commercialisation: polyphonic pygmy singing from Central Africa, ecstatic Sufi soul doctors from Pakistan, drone-drenched bagpipe players from Bulgaria or heart-invading praise singers from Mali. Souleyman is the singer in a small band that plays dabke music at weddings in Syria.

If there's one festival in Britain where people are ready for the rain, it's the Green Man. After all, nobody goes to the Brecon Beacons to sunbathe, right? The weekend, which began the spate of boutique and specialist festivals that dominate the summer season now, remains one of the most spirited in the UK, and its crowd seems to be one of the hardiest even when, as this year, the deluge is near-continuous.

The premise of Jonathan Bate’s one-man play, directed by Tom Cairns, is simple but surprisingly effective: a trawl through the seven ages of Shakespeare, from babe to box, told through a mixture of biographical narrative illuminated by relevant scenes from Will’s work.
