On October 26, Delia Gonzalez & Gavin Russom release what will “very likely” be their last recording together.

The 12″, which comes courtesy of DFA, is led by layered synthesizer epic ‘Track Five’. This piece was originally meant to be included on the duo’s celebrated 200- album Days Of Mars. Russom told us more about it in an interview earlier this year:

“‘Track 5′ was originally the last track on The Days of Mars. It came out of a studio jam that we did with Tim Goldsworthy during the sessions that produced the album and the ‘El Monte’ 12″. The original cut of Days of Mars was ‘Rise’ and ’13 Moons’ as they appear on the released version, and then the alternate version of ‘Relevee’ that appears on the single, and ‘Track 5′.

“In final edits we decided it didn’t fit on the record, conceptually, and we cut ‘Black Spring’ which fit perfectly. The major problem with ‘Track 5′ in terms of our releasing it then was that it was almost entirely machine-driven whereas most of the material on Days was played by hand. So we did a later session in Berlin and played back into the machine-made track with great results. It’s a departure from the sound on Days of Mars in certain ways, but it retains a very similar feel. It serves as a counterpart to ‘El Monte’, which was the first single we released.”

The 12″ includes a remix from German house heavywrights Âme. More info and pre-orders here.
