One of Scotland's smallest but most acclaimed music festivals today unveils its biggest programme yet.

Leading traditional acts Capercaillie, Roddy Hart & The Lonesome Fire, Skerryvore and Manran will all be appearing at the Tiree Music Festival, which is on July 20 and 21.

Named Scotland's best small festival at the Scottish Event Awards last year, the event is held next to the white sands of Crossapool Bay on the isle in the Inner Hebrides.

This year the festival, tickets for which are going on sale today, is expanding in size and has capacity for 1500 music fans.

Daniel Gillespie, the festival's artistic director, said: "After performing at festivals worldwide with [his band] Skerryvore I kept thinking how amazing it would be to have a festival on my home island of Tiree that would give something back to the locals and also attract new visitors.

"Fast forward four years and we are now approaching the fourth TMF, having achieved three successive sell-outs and the accolade of being awarded Scotland's Best Small Festival. It really is a dream come true. TMF 2013 will be our biggest festival to date and will once again showcase Tiree as one of the most stunning locations in the world."
