"Can't We Be Friends?" opens the 1956 Verve album Ella and Louis, one of the most beloved vocal recordings in jazz history, pairing Ella Fitzgerald and Louis Armstrong for the first time on disc. The Kay Swift standard, performed at a comfortable 110 beats per minute in B-flat major, features a half-chorus trumpet solo from Armstrong that exemplifies his late-career approach to ballad and medium-tempo material. His tone, burnished by decades of performing, retains its unmistakable warmth and rhythmic authority, each phrase placed with the unerring sense of timing that made him the foundational figure in jazz improvisation. The session was produced by Norman Granz with the Oscar Peterson Quartet providing accompaniment, including pianist Peterson, guitarist Herb Ellis, bassist Ray Brown, and drummer Buddy Rich. The album's concept paired the greatest jazz vocalist of all time with the man who essentially invented jazz singing, and the results justified the matchmaking. Fitzgerald's pristine intonation and rhythmic sophistication complement Armstrong's gravelly warmth and spontaneous humor. The 32-bar AABA form provides a familiar framework for the vocal interplay and Armstrong's trumpet statement, creating a performance that is simultaneously intimate and historically significant.
