Bird's Nest, recorded February 1, 1947, is a high-energy rhythm changes performance by the Charlie Parker Quartet at a very fast tempo of approximately 291-299 BPM in B-flat with a 32-bar AABA form based on I Got Rhythm. Parker's two-chorus alto saxophone solo launches directly into the performance without a composed theme, and Erroll Garner follows with two commanding choruses of piano that demonstrate his remarkable ability to maintain harmonic clarity and rhythmic drive at extreme tempos. The quartet setting with just Parker, Garner, Red Callender on bass, and Doc West on drums places the two lead voices in stark relief against each other. The contrast between Parker's sinuous, chromatic bop lines and Garner's block-chord, swing-rooted approach creates a fascinating stylistic dialogue. This recording is from Parker's first post-Camarillo session and demonstrates that his technical command and creative fire were undiminished. Bird's Nest captures two of jazz's most distinctive improvisers pushing each other forward at breakneck speed.
