Recorded on September 15, 1944, Tiny's Tempo is the earliest recording in this collection and one of Charlie Parker's first studio sessions as a sideman. Performed by the Tiny Grimes Quintet, the track is a medium-up swing blues in B-flat taken at around 212 BPM. Parker's three-chorus alto saxophone solo is already remarkably advanced, showcasing the fluid eighth-note lines and harmonic ingenuity that would define bebop. Pianist Clyde Hart contributes a two-chorus solo that bridges swing and bop idioms, while guitarist Tiny Grimes takes three choruses in his distinctive electric guitar style rooted in the swing tradition. The contrast between Grimes's swinging, blues-inflected approach and Parker's revolutionary vocabulary captures a pivotal moment in jazz history, documenting the transition from swing to bebop in real time. These Savoy sessions under Grimes's name gave the twenty-four-year-old Parker his first significant exposure on record, and his playing here already hints at the seismic impact he would soon have on the music.
