The first in the Space Age Series, and in my opinion, the best. Mix-master DJ Tisto turns up the beats with this great hit. One great feature, as with many DJ Tisto compilations, is that the fact that he makes some of his own music, so when you listen to it, you can legitimately ponder on what a great DJ, Tisto is. Songs like Groovelounge and Gimme Some Sugar really pack some bass. But my personal favourites are Flying Squirrel Problem and Perception 4. Perception 4 is not only a great song to dance to, but a melodic masterpiece as well. The only reason I didn't give it 5 stars is because the cd doesn't really start till track 7, if you listen to it, I think you will agree with me.
