Matthew Shipp Trio + Weasel Walter/Mary Halvorson/Peter Evans Trio

Intrepid imprint Thirsty Ear presents a striking double bill of trios that've cut recent discs for the label. Matthew Shipp, celebrating his 50th birthday, betrays no signs of slowing down on his latest release, the imposingly titled double disc The Art of the Improvisor. Sharing the bill is frenetic jazz-thrash drummer Weasel Walter, who prods a blistering three-way of his own.
