For today’s installment of Remix Roundup, we have three completely different but individually stellar tracks in their own right. First off is Sydney duo Olympic Ayres, who dropped the upbeat electro-gem “Take Flight” a few weeks back. While not actually a remix, this electronic original will have you taking flight in no time, and is due out on their forthcoming EP Leisureplex later this year. Next up is the sexy mashup of Foals “My Number” over Booka Shade’s “Charlotte,” by fellow Australian artist RÜFÜS. Grab the free download here, and catch them at U Street Music Hall March 27 if you’re in DC. Last but not least is the latest from Austrian producer Cid Rim, an electric remix of Sky Ferreira’s “You’re Not The One” replete with arpeggios, shiny vocals over a choppy chorus, and a punchy bass line — the stuff good remixes are made of. Stream all three below.
