Madlib, 'Beat Konducta, Vol. 5–6: A Tribute to...' (Stones Throw)

A quirky homage to hip-hop’s quixotic beatmaker.

The ghost of the late James “J Dilla” Yancey still haunts Madlib, who calls his musical comrade the “Coltrane of Beats” on this exuberantly melancholy tribute. With song titles like “In Jah’s Hands” and “Infinity Sound,” this may be the Beat Konducta’s most spiritual release to date.

Telefon Tel Aviv, 'Immolate Yourself' (Bpitch Control)

Trend-twiddling production duo use entire digital canvas.

For their third album, and first in five years, Chicago-based electro poppers Joshua Eustis and Charlie Cooper nod to recent "new disco" (Lindstrøm, Lifelike & Kris Menace) and "neo-trance" (Booka Shade, Mobilee crew) styles. But at heart, the twosome are still laptop experimentalists.

Mr. Oizo, 'Lambs Anger' (Ed Banger/Because Music)

Post–Flat Eric, French house vet deftly dices the funk.

For his third album, Quentin "Mr. Oizo" Dupieux rapaciously chops disco classics into two-minute mini-beats ("Positif," "Bruce Willis Is Dead") or debauched club-kid romps ("Two Takes It," with saucy rapper Carmen Castro).

Dälek, 'Gutter Tactics' (Ipecac)

What Soulja Boy hears in the Guantánamo of his mind.

Grindcore guitar, industrial clamor, stentorian rhymes?

Zion-I, 'The TakeOver (Gold Dust Media)

Bay Area hip-hop humanists still speaking truth to nihilism.

On their sixth album, this Oakland duo (plus guests Devin the Dude and Brother Ali) explicitly address an urban audience unbowed by class warfare and street crime. Unabashedly upbeat, MC Zumbi compares ghetto life to being a "caged bird," but even when he dismisses haters ("Burning incense, yeah, they tried to call us yoga"), he sounds optimistic.

Femi Kuti, 'Day by Day' (Mercer Street)

With the guest rappers gone, now the party can really jump.

On his first collection of original material since 2001's Fight to Win, Afrobeat scion Femi Kuti and his sprawling Positive Force ensemble unfurl 12 songs of serpentine rhythms and civic disobedience.
