Another year, another collection of ice-cold bangers.

In the midst of summer's heat, Greenhouse, the partnership between Columbus rap luminaries Blueprint and Illogic, are set to release "Electric Purgatory, Vol. 2," the second installment of their wintry EP series, on Blueprint's own Weightless Recordings.

For the second year in a row, when the weather got cold, Blueprint locked himself indoors and started cranking out dark, despairing, "bugged-out" beats. Creeping classical strings, eerie synth lines and cynical movie samples were the order of the day.

"Whenever I sit down that first weekend when it gets cold and you don't want to leave your house, it seems like all my music starts sounding like that," Blueprint said.

Having just released the first "Electric Purgatory" EP, Blueprint was eager to recapture the chemistry that produced highlights like "Cold Out There." So he once again invited Illogic over to collaborate.

Lyrically, struggle remained a primary theme, but where the first record tackled the trials and tribulations of the underdog rapper, this one took a more universal tack.

"It's more the struggles of a person - the person that is the artist," Illogic said.

The seven-song set features cameos from Aesop Rock and Toki Wright. The latter rapper will join Zero Star, Stonecraft and DJ Rare Groove at Saturday's Skully's release party.

Both Greenhouse rappers have several more releases on the horizon. The duo has a much "brighter, bouncier" full-length in the can, but that won't see the light of day until Blueprint's next solo album drops this fall on Minnesota's esteemed Rhymesayers label. For his part, Illogic is working on an album with producer Blockhead and is readying a collection of unreleased tracks.
