"One O'Clock Jump" is Count Basie's signature composition, and this 1955 Pres & Sweets rendition carries special significance given that both Young and Edison were key members of the Basie orchestra during its golden era. Taken at a blazing 236 BPM, the track opens with four choruses of solo piano from Oscar Peterson, who channels the Basie spirit while displaying his own staggering technique. Young then takes an extended seven-chorus tenor saxophone solo, one of the longest statements on the album, building through the blues form with the relaxed swing that had defined his playing since the late 1930s. Edison closes with five choruses of trumpet, his punchy, riff-based approach perfectly suited to this Basie-associated material. The performance functions as both a tribute to the Count Basie Orchestra tradition and a demonstration of how jazz musicians carry their musical heritage forward into new contexts. The blues form in D-flat provides an open canvas for extended improvisation, and all three soloists rise to the occasion with playing that honors the communal spirit of the big band while exploiting the freedom of a small-group setting.
