Vocalist Luba Mason has no desire to be hemmed in by labels or categories. Instead, she’s made a declaration of independence with the 12 disparate tracks on her latest release, Mixtura (Kobalt), which lean toward the jazzy end of the spectrum. The album’s title hints at the eclecticism Mason offers, whether she’s performing a Brazil-tinged version of James Taylor’s “On the 4th of July” with Dori Caymmi and Kenny Loggins adding vocal backgrounds, or engaging in a zippy flamenco-style duet with Al Jarreau on Van Morrison’s “Moondance.” The opening track on Mixtura, and our selection, “Freedom” offers a statement of purpose. Mason, who’s married to singer-actor Rubén Blades, receives support from A-list guests such as trumpeter Randy Brecker, bassist Jimmy Haslip and percussionist Bobby Allende. Against a funky fusion groove spiked by the vibes and percussion of musical director Felipe Fournier, the singer delivers a powerful message of self-determination.
