Old Knew is Gregory Groover Jr’s follow-up to his 2024 Criss Cross debut, Lovabye. On Old Knew, Groover addresses similarly inspired repertoire from a different angle, eliciting collective kineticism and creative spirit from a pan-generational A-list quintet, comprising Ross, the nonpareil 30-year-old vibraphonist; Paul Cornish, the 20-something pianist; and the glorious drummer Kendrick Scott and bass provocateur Harish Raghavan. There’s also a theme on this record, but I wanted the energy to feel different, less about the written composition and the mood, and more about the interaction and my playing.” Towards that aspiration, Groover wrote or arranged another 11 pieces tailored to the idiosyncratic tonal personalities of his bandmates, who color and characterize the music.
