BIFFY CLYRO, CHVRCHES, Mogwai and Edwyn Collins are among the acts vying for one of the country's top music prizes.

The Scottish Music Industry Association (SMIA) has revealed the bands in the running for the Scottish Album of the Year (SAY) Award.

Returning for a third year, the list shows a wide variety of music styles - from jazz and chamber to pop, rock and indie.

Bands involved include Scottish mainstays and groups releasing their debut albums.

Vic Galloway, SAY Award Host said: "This is possibly the strongest list the award has seen yet, and proves the diversity and quality across a range of rock, indie, pop, hip-hop, electronica, jazz and classical music.

"All 20 deserve your attention and investigation, representing the artistic cream of the crop from this extremely talented land."

Music fans will get their chance to vote for their favourite album following a four-week promotion of the albums on the longlist.

From Monday, the public can stream one of the 20 longlisted titles each week day. There will then be a 72-hour public vote starting on May 26.

Other acts in the running are Frightened Rabbit, Camera Obscura, Kid Canaveral and Roddy Hart and the Lonesome Fire.
