"Billie's Bounce" is a classic bebop blues head composed by Charlie Parker, first recorded in 1945 during Parker's landmark session for Savoy Records. On Harold Mabern's 2014 album Afro Blue, the tune is performed in its traditional key of F with a 12-bar blues form at approximately 180 beats per minute, honoring the bebop tradition while bringing the assembled musicians' collective fire to the material. This recording features four soloists, making it one of the album's most solo-intensive tracks. Vocalist Kurt Elling opens with three choruses of vocalese-influenced improvisation, bringing his distinctive approach to the Parker blues -- a noteworthy pairing given that singers rarely tackle this instrumental staple. Trumpeter Jeremy Pelt follows with three choruses of bright, articulate trumpet work. Mabern takes two choruses on piano, his blues-rooted playing perfectly at home in this quintessential bebop blues context. Tenor saxophonist Eric Alexander closes the solo section with three commanding choruses, circling back to the saxophone tradition from which the composition originated. The sequence of soloists creates a narrative arc that moves from voice to brass to piano to saxophone, offering the listener four distinct perspectives on the same 12-bar form. The inclusion of Elling adds a vocal dimension that connects the performance to the vocalese tradition of Eddie Jefferson and Jon Hendricks.
