The boundary-flouting farsightedness of guitarist, composer and bandleader Mary Halvorson is at its peak on Away With You. It finds her reconvening the septet with which she performed on her captivating Illusionary Sea (2013) and add an eighth member, pedal steel guitarist Susan Alcorn. The new recruit is no stranger herself to straddling stylistic forms, her maverick aesthetic encompassing outlaw country, twisted tangos, classical composition and beyond, deep into the realms of improvisation. Here, though, Alcorn deploys a flurry of clean, silvery-singing slides and sharp staccato stabs, tones arguably more identifiable with the instrument's conservative pedigree. But the Octet busies itself to run a scurry of bustling ideas and explosive set-pieces within which to relocate and assimilate her glistening, sometimes willowy, chimes, obfuscating the memories of a genre-specific habit along the way. Halvorson in particular seems buoyed by the fresh spectral presence, joyously skittering spider-like about her frets, only occasionally settling on the barebones of folk music and plush pop refrains (as on the title-track), for a well-earned breather.
