Thirty-eight years ago a trombonist with the unlikely name (for a Latin jazz musician) of Mark Weinstein released one of the most innovative albums in Latin Jazz ever heard then, Cuban Roots. If you’re fortunate enough to snag a copy, you may quickly discover that is sounds as fresh now as it did then.

Now picture Weinstein in 2005, older and musically even more sophisticated, playing flute rather than trombone. And rather than playing in a typical brass-heavy Latin jazz band, he surrounds himself with a highly eccentric jazz-rock guitarist, a vocalist who sweetly sings Santeria chants, a Latin jazz acoustic bass player, and a battery of Cuban drummers. This adds up to one of the most original blends of jazz and Cuban music heard in recent years, quirky, lively and as singular as Weinstein’s 1967 masterpiece.

The 10 tunes comprising Algo Mas include a variety of improvisations grounded in rumba and Santeria songs. Two instrumental voices are dominant throughout. Weinstein forcefully and lyrically plays soprano, alto and bass flutes, some times overdubbing all three to create a massive, intense vocalized sound. Electric and electrifying guitarist Jean Paul Bourelly skitters about the frets with lots of Afro-pop, jazz and avant-rock colors, and with more that a touch of the runs you might identify with Jimi Hendrix. This adds an odd but appealing edginess to the music, as if you expect the band to veer into an Afro-Cuban version of “Foxy Lady” at any second. Just to make this musical gumbo a little more odd, there’s vocalist Pedro Martinez, who sings Santeria chants with great fervor and traditional styling, seemingly oblivious to Bourelly’s noisy neo-psychedelic runs and Weinstein’ post-bop flute flights.

This is intellectually deep and emotionally satisfying jazz improvisation on Cuban themes that demands and rewards close listening, a recording for those who want to adventure beyond much of the formulaic arrangements that pass as ‘Latin jazz’ today. And you can dance to it, although you’ll have to create some strikingly new moves to keep up with this music’s daring spirit.
