UK chaotic hardcore specialists Rolo Tomassi are set to release new single 'Old Mystics' on March 27. The track is now streaming on the group's official Facebook page.

'Old Mystics' is the first single to be recorded with new members Chris Cayford and Nathan Fairweather, who have recently joined the band. This follows the departure of Joe Nicholson and Joe Thorpe from the band. Bassist Nathan Fairweather plays in Brontide, while guitarist Chris Cayford joins from No Coast.

Rolo Tomassi recorded 'Old Mystics' with producer Jason Sanderson, who also worked with the band on their 2008 'Hysterics' album. The new single will also be featured on the group's third studio album, which will be released later this spring. It will be backed with b-side 'Mesmerizer'. The single, and new album, will be released via the band's own Destination Moon label.

"We are delighted to be able to welcome Chris and Nathan to the band. Both of them have great backgrounds in other bands we've been fans of and have been long-term friends of ours," said vocalist Eva Spence.

"It's an exciting time and we can't wait for people to hear what we do next," added keyboardist and vocalist James Spence.

Live wise, the band head off as main support on the April Architects UK dates, full list of dates are also up on the bands Facebook page.
