On "Liminality," Chicago guitarist Erik Skov creates a striking debut, exploring a far-reaching collection of original compositions with his six-piece ensemble, including saxophonist Dustin Laurenzi, trumpeter Emily Kuhn, trombonist Euan Edmonds, bassist Kitt Lyles, and drummer Gustavo Cortinas. Referring here to the threshold between stages of a transformative process, "Liminality" celebrates that zone where creative discovery and possibility can thrive, through long-form compositions rife with unfolding melodies, elegiac set pieces, or straight-ahead romps.
