REIGNING Scottish album of the year winner Kathyrn Joseph is one of the top musical attractions as Scotland's festival of ideas - sponsored by the Sunday Herald - returns in September.

Joseph who won the 2015 Scottish Album of the Year award last month for her album Bones You Have Thrown Me, And Blood I've Spilled is amongst a host of headline speakers and artists lined up for the second Imagination: Scotland's Festival of Ideas.

The brainchild of writer Gerry Hassan the festival will include the Sunday Herald debate on the future of Scotland, discussions on the Greek and European crises, social change, the role of arts and culture, Labour after the election, and the legacy of Upper Clyde Shipbuilders work-in.

A series of discussions throughout the Sunday Herald-sponsored weekend will look at how ideas can be put into action and how Scotland wants to define itself in the near-future.

The festival which runs from September 4-6 is said, by the organisers, to be bigger, more varied and diverse than last year in its range and ambitions.

There will also be historic tours. The first walking tour at Glasgow Central station, goes behind the scenes, and gives an in-depth look at the history and events which have passed through it. The second with the Scottish Football Museum criss-crosses the city visiting some of the most notable historic football sites in Glasgow.

Speakers include Will Hutton, Richard Holloway, Andy Wightman, Sunder Katwala, Zoe Williams, David Goldblatt and Fintan O'Toole.

Hassan said: "After last year's successful and vibrant festival of ideas it is great to be back, bigger, more varied and putting on lots of interesting things about Scotland, the world and life, asking really challenging questions and hosting wonderful topics and discussions."

Richard Walker, editor of the Sunday Herald said: "It is great that for the second year that the paper is sponsoring and involved in Imagination: Scotland's Festival of Ideas. Last year's gathering was a wonderful set of events at one of the most important points in Scotland's history. This year is going to be even better and more vital and illuminating."
