This may be Freddie Hubbard's finest moment as a leader, in that it embodies and utilizes all of his strengths as a composer, soloist, and frontman. On Red Clay, Hubbard combines hard bop's glorious blues-out past with the soulful innovations of mainstream jazz in the 1960s, and reads them through the chunky groove innovations of 1970s jazz fusion. This session places the trumpeter in the company of giants such as tenor saxophonist Joe Henderson, pianist Herbie Hancock, bassist Ron Carter, and drummer Lenny White. Hubbard's five compositions all come from deep inside blues territory; these shaded notions are grafted onto funky hard bop melodies worthy of Horace Silver's finest tunes, and are layered inside the smoothed-over cadences of shimmering, steaming soul. This is a classic, hands down.
