Stupendous, recorded February 26, 1947, is a contrafact based on the chord changes of 'S Wonderful, performed by Charlie Parker's New Stars at approximately 231-234 BPM in E-flat with a 32-bar AABA form. Composed by Howard McGhee, the track features a parade of soloists: Parker opens with a full chorus of alto saxophone, followed by McGhee for a half-chorus on trumpet, Dodo Marmarosa for a half-chorus on piano, Wardell Gray for a half-chorus on tenor saxophone, and Barney Kessel for a half-chorus on electric guitar. The Gershwin changes provide a harmonically rich framework that differs from the more common rhythm changes and blues vehicles of the era, and each soloist navigates the progression with individual flair. Parker's full-chorus solo demonstrates his ability to bring the same level of invention to any set of changes, while the shorter solos from the other musicians provide contrasting textures and approaches. This large-ensemble Dial session recording is a testament to the depth of talent assembled for Parker's West Coast dates.
