Not much to add to the other 20 reviews (yes 20, compare to the average number of reviews on CDs in the rest of Amazon's trance chart, regardless of the chart placing, and you'll get an idea about how much more affecting these guys' music is than most)... but, having had time to really digest it I'll wade in anyway, as any new A&B artist release is bound to be worth a few words.
As other reviewers have suggested, maybe just one additional vocalist (Ashley Tomberlin, for example?) might have added another layer of interest, and the instrumental tracks, while complementing the vocal ones, don't even seem to pack the same punch as on the classic Tri-State, from which the "sound" has not evolved much. Don't see that as a negative, though - it's just another collection of quality melodic trance for you to enjoy.
Some of the songs, although very thematically simple, are lyrically interesting (Alchemy), others go into deeper storytelling (Black Room Boy); if you want banging, chunky basslines, then You Got To Go, Black Room Boy and Giving It Out all deliver in spades, while Zoe Johnston serves up a tear-jerking tour de force on Only A Few Things which is every bit as memorable as Good For Me was on Tri-State.(You can easily imagine her re-recording this in her folky, acoustic solo style to devastating effect.)
But yep, there are a few slices of super-strong cheese, too. On My Way to Heaven would have benefited from lines and superfluous lines of Richard Bedford's lyric having been cut from the opening, at least until after the kick drum got going, giving the track more of a chance to develop, and on the chorus of Thing Called Love, you're thinking: "Hold on, did he really just rhyme 'forget' with 'regret', and then 'forget' again?"
Such gripes aside, Above & Beyond have made Xmas shopping for stocking-fillers a hell of a lot easier, as I know a few people who will really appreciate Group Therapy.
