Aight, still not fully to compare with the third chapter of the series (ISOS 3), but the diversity and quality in CD 2 beats the hell out of ISOS 4 & 5 (except of few exceptions) !
CD 1 is good, with some soft melodic progressive and chillout tracks starting with that great intro, and especially with the special In Search Of Sunrise edition to grow on us nicely.
CD 2 just wins it for me, the trancy intro builing up a solid background, backed-up with beautiful vocals then wonderfully switching to some good House-ish sounds in order to create a gorgeous diversity in this second side is definitely worth the win. A nice Ambient, Energetic, Soulful, Sensual and Emotional sound, satisfies lots of tastes in the Music industry. Besides, some catchy noticeable Old-School sounds around the end, very nice compiled.
