All of these songs are QUALITY. The production in these songs are simply amazing. It's deep, trancey minimalistic dub that will blow speakers out with the amount of sub-bass they contain. I strongly recommend to only listen to these tracks on a good soundsystem to fully grasp the intentions of every song. Some of the tracks that speak most to me would be starting with Vishnu "David Makes Triangles" which has very clear highs and lows, lows so deep my bassbin can't even comprehend, very lullaby like. All of the Indigo, King Slaff and DFRNT tracks are also mindnumbingly incredible but for the sake of this review I'll leave it at that. Furreshu "The Leopard" has to be one of the best tracks I've ever heard. Its synesthetic creep creates a very vivid eerie picture that is incredibly precise and beautiful. Tangka "the Salamander" paints exactly the same dark picture that is unique to this compilation. My recommendation to anybody who hasn't heard any of these tracks is expect to hear something that is different from most dub step out there. Truly a one of a kind masterpiece that you find very rarely in music these days.

This is a great cd mixed by two of the best producers. The track listing is Ace. It starts off trancey and very mellow but by the middle things pick up intensely and then slows it back down to smooth lovemaking songs again. The mixing isn't anything special, most of it is just one track cut to the other.
I enjoy listening but what this cd doesn't carry is the vibe of a real dubstep show. The rewinds, mc, shaking bass none of that is experienced. It's might sound odd to say but the music in this case is only a part of the experience. If you want to know what real dubstep is like go and hear it outside of your house.

This cd really captures what happy hardcore is all about through its energetic songs and fun in the mix. I would say it is a great cd to add to a happy hardcore collection or to begin one with.

Hardcore Heaven 4 is an impressive cd full of hardcore and happy hardcore favs.
CD1- Scott Brown mixes this up okay but there is alot of unecessary breaks and really doesn't pick up until J. Ritmen's "303 Freestyle" plunges in with its mega-uplifting synth which is ok but really makes the other songs sound alot more bland.
CD2- The best out of the 3 definitely. Kevin Energy makes an overwhelming intro with Splash "Blame the Moon" leaving the euphoric feeling with you all the way to the next peak.
CD3- I find this to be mildly pleasant with no real "moments" in the cd itself. Can get a little boorish at some points.
Overall I would recommend this cd to buy if you are a major hardcore fan. I could see how a listener of a different style could at first not interpret the structure of the cd and its tracks but it would surely be understandable after the third good listen.
