"SB-08" follows last year's 19-and-a-half-minute "SB-07" instrumental, continuing the band's annual tradition of releasing a lengthy instrumental for fans to enjoy at Christmas.

The band haven't released any new music this year aside from their annual instrumental, and are yet to follow up their 2018 album IC-01 Hanoi.

Unknown Mortal Orchestra's "SB-08" track is out now.
