Jim Hall (1930–2013), guitarist-composer whose lyricism, harmonic subtlety and use of space reshaped modern jazz guitar. From early chamber-jazz with Chico Hamilton and Jimmy Giuffre to Sonny Rollins’s The Bridge era, he excelled in conversational trios and duos. Essentials: Undercurrent and Intermodulation (with Bill Evans), CTI’s Concierto, and the duo Alone Together with Ron Carter.
