The album title refers to the union of ivory (piano) and slide (trombone). No doubt, they’ve crafted a cohesive musical relationship via pumping grooves and buoyant undercurrents. Blaser morphs sonorous lines with cunning improvisational phrasings in concert with Braff’s powerful chord clusters and shrewdly enacted rhythmic maneuvers.
Marked by quite a bit of pop and sizzle, the duo tones it down in spots, yet execute a thrusting rendition of "Caravan," where the artists redefine the primary theme via swerving dialogues and gobs of counterpoint. In other regions of sound, they delve into bluesy, and soul-drenched motifs amid avant-garde style workouts. Hence, they expand, contract and explore.
The harmonically endearing title track "YaY," is the album opener, and they close it out with the same piece, which was recorded at a live venue. In sum, the musicians convey a great deal of poise and strength flex while rendering strong compositions that impart a lasting impression. It’s a standout release, indeed.
