After the intermission Corea and Burton returned to the stage and upped the ante, adding the Harlem String Quartet to the piano/vibes variations. Since it was their first-ever performance with HS4, they leaned a bit heavier on the past, leading off with a couple of the opening movements from Corea’s “Lyric Suite for Sextet” and encoring with the lilting “Brasilia” from the same 1982 album. But they also dove headlong into “‘Round Midnight,” the strings adding considerable tonal depth and a sweeping, cinematic atmosphere to Thelonious Monk’s classic. And they brought it all home with another new Corea composition, the rumba groove of “Mozart Goes Dancing,” the only selection from “Hot House” that features the Harlem String Quartet.
