Tristano recorded his first album for Atlantic Records in 1955; he was allowed control over the recording process and what to release. The eponymous album included solo and trio tracks that contained further experiments with multitracking ("Requiem" and "Turkish Mambo") and altered tape-speed ("Line Up" and "East 32nd"). The use of overdubbing and tape manipulation was controversial with some critics and musicians at the time. "Requiem", a tribute to Parker, who had died a short time earlier, has a deep blues feeling – a style not usually associated with Tristano. For "Line Up" and "East 32nd", Tristano's "use of chromatic harmony ... secures him a position of a pioneer in expanding the harmonic vocabulary of jazz improvisation", in biographer Eunmi Shim's words.
