He said, "coming real soon. 5 years of mau5. remixes by chuckie, dillon francis, nero, eric pryds [sic], nero, madeon, pig n dan, botnik [sic] and more :)." Today, deadmau5 unveiled the release date of 5 years of mau5: November 25th, 2014. On top of that, it will be a double album. This means we'll get to hear a lot of deadmau5 tracks reimagined.
The album art for 5 years of mau5 is a combination of his previous album covers.
We don't know much about which songs will be remixed, but we do know that Dillon Francis remixed "Some Chords" for the album. He debuted an unfinished version of the remix at Mad Decent Block Party on August 31st.
