After a noticeable disappearance and a blog post about the issue, it seems that Kaskade has finally returned to the olden days of Kaskade Mashup Mondays — with two tracks this week no less. Last week he combined a Nicky Romero remix with “Angel On My Shoulder,” and this week he brings us into the early hours of the mornings with “4 AM Quasar” and “Invisible at 5AM.” Kaskade uses his favorite trick of combining big tracks with recognizable acapellas from his own collection, and the results are fresh and different. As usual, the tracks are available as free downloads from Kaskade’s SoundCloud (and below), so be sure to show him some love on Twitter with the hashtag #KMM if you’re a fan of the new additions to your iTunes library.
