There's a delicious simplicity to the concept behind Rawax's Aira series, which involves much-lauded producers creating new tracks entirely using Roland's retro-futurist equipment series of the same name. Given Ron Trent's association with the machines the series was inspired by - TR-909, TB-303 etc. - he was clearly an obvious choice to get involved. As usual, he's conjured up some classically melodious, evocative and emotion-rich material. "Deep In The Stars" sees him in late '80s/early '90s deep house mode, with twittering melodies and ocean-deep pads wrapping themselves around a decidedly tactile groove. "Rock The Box" is typically expansive, with robotic vocals and a whisper of electro amongst the sweeping chords and intricate synthesizer motifs.
