Intriguing conversant duets are delivered by Timothy McAllister on alto or soprano sax alongside pianist Liz Ames. The two create a wide spectrum of moods and colors, forming a graceful unison trail on “Painting With Knives” with McAllister’s alto sax puffing or squawking alongside Ames’ musings on “Nina Shekhar”. On soprano, McAllister is a bit edgy and assertive around Ames’ rich strides on “Discordant Metamorphosis…” while getting romantic on the flowing “Elegy”. The two jab like middleweights on the punchy “Get Up!” and are most jazzy on the bright “Obstacle Illusion”, but throughout the two work well with volleys, relays and responses. Modern sonatas.
