Last week Villa released the Best of 2011 installment of their "in the mix" series. This mix features 50 different tracks and remixes and yet is only an hour long. It jumps from track to track rather rapidly but is a nice look back on some really good tunes from the past year.
Tronik Youth also just put out a Best of 2011 mix. This one spends a little more time on each track as it is around 30 tracks and just under and hour and half. Another great mix of some of the best tunes of the year.
Yuksek just posted this mix he did for Triple J radio. I haven't gotten a chance to listen to it yet because of all of the other material that has come out recently. I am excited to get to it though because Yuksek doesn't post many mixes on his soundcloud page. From the tracklist it looks like about half Yuksek tracks/remixes and half tracks and remixes from other artists.
