Finland's Verneri Pohjola got five stars in these pages last year for his sumptuously colourful big-band album Aurora. Ancient History is for the trumpeter's quartet with the daring pianist Aki Rissanen, and though it isn't as atmospheric, it has a comparable thematic strength and plenty of compelling improvising. The only cover is of Björk's lyrical Hyperballad, which Pohjola explores in half-valve slurs and sighs (he has affinities with Norway's Arve Henriksen and America's Ambrose Akinmusire) mingled with hints of postbop phrasing against a scramble of free percussion.
