Incorporating elements of traditional Mexican and Spanish music into his expansive repertoire, tireless composer John Zorn bangs out another soundtrack, this time for a documentary about Mexican dictator Plutarco Elias. Another accessible, beautiful release, El General is scored for guitar, marimba, bass, piano, and accordion, with drums and vibraphone showing up in spurts.

Mountains: Choral (Thrill Jockey)

Making its Thrill Jockey debut, this electro-acoustic duo creates acoustic melodies that breathe with the field recordings and electronics that surround them. Tranquil, crackling bits pile on layers of atmosphere; drones circle around extended passages and repetitive themes. The result is a serene album that is as apt for detached meditation as it is for intense musical focus.

Rob Mazurek Quintet: Sound Is (Delmark)

Following a solo release and albums from Sao Paulo Underground and Exploding Star Orchestra, jazz composer/cornetist Rob Mazurek returns with a new quintet. The group features a loaded lineup of Chicago standouts, including drummer John Herndon (Tortoise), vibraphonist Jason Adasiewicz (Rolldown), acoustic bassist Josh Abrams (Black Earth Ensemble), and electric bassist Matthew Lux (Isotope 217).

With 14 new compositions, Sound Is sees Mazurek continuing to push the boundaries of modern jazz while using semi-traditional instruments.

Steven Wilson: Insurgentes (Kscope)

The founder of English rock band Porcupine Tree, guitarist/singer Steven Wilson has taken a wandering path throughout his musical career, traveling through metal, pop rock, progressive psychedelia, and atmospheric ballads.

Wilson's solo debut, Insurgentes, shows a similar penchant for diversity. Rock structures overlap with electronic ambiance, moody acoustic guitars, dark synths, and soft vocal harmonies, making a malleable foundation as Wilson channels Thom Yorke in much of his signing.

A bit of the balladry gets too close to Coldplay and other melodramatic radio artists, but most of the album is an interesting exhibition in songwriting.
