Parisian big room evangelist Michael Calfan has had a softer step to his boots of late. Digressing from the key driven energy of “Prelude” to more recent docile house offering “Treasured Soul,” the New Year indicated a leap towards the sound on everyone’s agenda for this sparing studio whizz. With the aforementioned original still in heavy rotation, Calfan dons his hand to label mate and Dutch house aficionado Oliver Heldens, bringing that maintained melodic stamina to instrumental version of “Koala” for Spinnin’s opening remarks of 2015. Calfan’s recent transformation is hard to slam on the merits of quality, but still takes some digesting given the resonance his earlier offerings for Axtone and the like left on the global industry. Behind the reigns of “Koala,” tempered keys and chunky grooves bring things back to life for the resurrected sound of this sparing French heavyweight, one that immediately trumps his prior Spinnin’ single. Fans are just going to have to deal with the fact that Michael Calfan is not batting for the big room sound anymore, as this latest remix is yet further testament to how comfortable the European heavyweight sounds in this new suit of house-favouring output.
