Some of the most potent recordings of Freddie Hubbard capture the hard-bop pioneer piercing into the avant-garde. The sprawling “Straight Life” has the trumpeter scuffing up his ebullient tone over funky soul, and he and alto player James Spaulding trade fierce cries over busy conga on “Backlash”. “Povo” is a fusion jam with a luxurious facade concealing a groove with tons of freedom in its swing.
