According to Blabbermouth.net, Stone Sour frontman Corey Taylor played an acoustic version of a brand new song, "Taciturn", at the Nova Rock festival on June 10 and at the Download festival on June 9.
Fan-filmed video footage of both performances can be seen below.
"Taciturn" will appear on Stone Sour's fourth album, "House Of Gold And Bones", a two-part concept effort which is being recorded at Sound Farm Studios, just outside Stone Sour's home base of Des Moines, Iowa, with producer David Bottrill.
According to Taylor, part 1 will contain 12 songs and will be released in October via Roadrunner Records, with the second 12-track part to follow next year. Each disc will include one half of the story, the lyrics for which fans will have to visit the band's official web site.
Taylor says, "Once I lock in the company who will help me put it together, there will be a comic book as well." Other songtitles set to appear on the album include "Absolute Zero", "RU486" and "A Rumor Of Skin".
As previously reported, Skid Row's Rachel Bolan laid down the bass tracks for the new Stone Sour CD. He has described the material on the record as "fucking fierce."
