With this solo set of seven originals, two Thelonious Monk themes and three standards, Lynne Arriale, a former classical pianist from Milwaukee, has taken a long-postponed plunge into unaccompanied performance. Arriale isn't an edgy artist, and she isn't as cannily slow-burning as Brad Mehldau, or as virtuosically soulful as Keith Jarrett – but her relationship with a piano has much of the late Bill Evans's quietly passionate devotion. The Chick Corea-like opener La Noche nudges a soft sway with an audacious flexibility of pulse, and the slow-rolling ballad The Dove is like an offhandedly entranced Abdullah Ibrahim. For the Monk tunes Evidence and Bye-Ya, she imparts the rhythmic shapes to a series of riffs but hides the melodies, and What Is This Thing Called Love threads elegant improv through punchy chordwork. The accents in Arialle's swing don't always sound nailed – the sumptuously rippling ballad is her real forte, as the tracks Arise, Dance and the swelling Will o' the Wisp confirm here – but her harmonic and melodic resources have rarely sounded in more inventive fettle.
