While Optimo are undoubtedly men-for-all-seasons musically, as anyone who's seen them in action behind the decks will attest, they're often at their best when creating a mood, delving deep into their bulging record collections to showcase sludgy curiosities, dark electronics and intoxicating oddities. Pleasingly, it's this side of their multiple personalities that's explored on Dark Was The Night, their sixth commercially available mix CD. Predictably, it's a doozy, effortlessly joining the dots between the moody deep acid house of QX-1's "I Won't Hurt You", the pulsating industrial rhythms of Carter Tutti, the icy melodies and snowy rhythms of Recondite's "Cleric", and the paranoid dubstep of Kode 9 and Space Ape.
