With a programme that so far has included US jazz-rock fusion heavyweights Yellowjackets, the Henry Threadgill-inspired improv of the acclaimed Trio Red, a sold out slice of New Orleans with  Hot 8 Brass Band, pianist Brian Kellock playing the music of Fats Waller, the intriguingly monikered Trio Elf at the Blue Lamp, as well as blues hero Mud Morganfield, gospel from Ruby Turner, and Courtney Pine, the festival moves to a conclusion tonight with Trio Libero featuring the ‘King of Aberdeen’ himself: Polar Bear’s Seb Rochford. The open-minded trio with Rochford joined by Andy Sheppard and Michel Benita make their Scottish debut. More at www.aberdeenjazzfestival.com
