Why aren't there more things out there at this duration? Just under half an hour of quick-witted improvisation from Ingar Zach and Ivar Grydeland at the Kongsberg Jazzfestival 2010. The engine room end of No Spaghetti Edition has a well-attested relationship as a duo, notably on «You should have seen me before we first met», also made for Zach's SOFA imprint, but this is exceptional, a series of overlapping enquiries, encounters that don't immediately seem like a meeting of minds but don't sound antagonistic either, unison swerves and a delicately distributed leavening of silence between the brittle, fragmentary tones.
