Amidst the trio recordings of the Exclusively For My Friends series, this Vol 4 stands out as a special feature. It is Oscar Peterson's very first solo album, where he can play unrestrictedly on the keyboard of his abilities--inspired by the ideal recording conditions he found in Hans Georg Brunner-Schwer's Villingen studio. It is no coincidence that this LP is still considered a revelation for Peterson fans, as the nine tracks exemplify all his skills. There are the grand, Art Tatum-inspired runs in Someone To Watch Over Me, the fiery and intricate rhythm of Perdido, and the clever pedal work in Body & Soul. In Bye, Bye Blackbird, he develops the theme and improvisation as if in a showcase, while with the charming miniature Lulu's Back In Town, he presents himself humorously. In Take The 'A' Train, he reveals the tricks by which a classic can gain personal notes. Then there is Peterson's quiet side, with the sensitive introspection of Who Can I Turn To and the overwhelming, deep-night tenderness of Little Girl Blue. The best jazz piano album ever made, judged the Canadian author Gene Lees at the time
