In a cryptic Facebook post reading "SOON", Ulver revealed the album art for their upcoming record, titled Messe I.X-VI.X. The album was recorded with the Tromsø Chamber Orchestra. Messe's material grew from a concert performance by both Ulver and the orchestra in 2012.
The band had this to say about the performance:
"The mass is new electronic/symphonic music specifically written for the evening, and it is grave. Again we go to the job with great humility and a dash of horror. The performance will be recorded and form the basis of Ulver’s next full-fledged album. Those expecting rock opera… Think again."
