With Out Here, premier bassist Christian McBride’s fifth recording on Mack Avenue Records, McBride introduces his latest working group: a trio, fully embracing at age 41 his role as standard-bearer and mentor. Pianist Christian Sands and drummer Ulysses Owens, Jr.—both younger, emerging artists—have been performing with McBride’s smallest group for about three years, honing their trio conception to a fine point of expressive depth and nuance with select performances around the world.
