The new album from the Unthanks takes them further along the folk/jazz/ambient route they are ascending with increasing confidence on each album.
Lots of reviews have pointed out a Gil Evans influence to the longer jazz inflected tracks, though a more contemporary influence would be both the works of Robert Wyatt and the Cinematic Orchestra.
They had a fun launch party, worth watching for a brief interview with the aforesaid Robert Wyatt.
