Unlike other electronic musicians, the Chemicals don't mind vocals and guitars. "Out of Control" from Surrender sounded like New Order, so the duo decided to ask Sumner to sing vocals. In this way, the Chemicals are much more accessible than sample-based groups.
The electro "Music: Response" is most similar to the Chemicals' previous work. "Music: Response (Gentleman Thief Mix)" adds more percussive elements and revs up the dance beat. The groovy "Music: Response (Futureshock Main Response)" is a likely club hit. The real treasure, though, is "Enjoyed." Unabashedly techno with all sorts of whirrs and sparks, it's like music for computers.
Music: Response is a great little piece for collectors or rabid fans, but it's nowhere close to the versatility shown on Surrender.
