As with many trance compilation albums nowadays, many of the tracks aren't actually trance. This is the way that the music scene is heading at the moment it seems, with electro gradually filtering its way into many high profile trance albums. ISoS10 is no exception unfortunately. I appreciate the ISoS series has always been about showcasing its own unique genre of trance, which I guess may not have actually been trance, but either way, we are seeing the what is now the typical electro inclusion. Something I personally just don't like. Granted, the tracks in question (most prevalent on CD2) aren't as severe as some of the tracks on other 'trance' compilations, but they are still there. Those tracks that contain the really annoying long pitch bends that act as a build up are the ones to look out for...
None of the Richard Durand offerings have been as good as the Tiesto era, in my opinion; ISoS5, for example, was fantastic, and nothing has quite hit the same heights since. However I think RD's mixing has improved over time, and in that respect I would argue that volume 10 is the best example of RD's mixing ability. Also, there are still some good tracks on the album; I particularly like Super8 & Tab's 'Black in Back' which is a throwback to about the mid naughties... a cracking song with proper trance grooves and complimentary vocals. There are one or two more typical 'Sunrise' tracks too, that are less club-like than many traditional trance songs, containing softer beats and synths. So it's not all bad.
I also appreciate that many people will enjoy this shift from trance (or whatever you want to call it) to electro (or whatever you want to call it), but personally I just think the emotions that you get with the former cannot be re-created with the latter, which is a shame. To me, you could throw all of the electro tracks on this album together with others from other recent 'trance' compilation albums and I couldn't tell them apart. Moreover, I wouldn't enjoy any of them. It wouldn't matter whether they were Searching for Sunrise or playing on Anjunabeach, they all sound the same; emotionless and cluttered (in my opinion...)
Enjoy ISoS10 for the odd glimmer of classic Sunrise and the odd pure trance stormer... but nothing more.
