Compiling tracks never before released on CD format, Tresor's Annex 2 focuses primarily on tracks from 12" EPs, meaning that most of the included songs tend to be dancefloor orientated, rather than intended for home listening. This tendency isn't necessarily a negative characteristic, and actually ends up making this somewhat of a more enjoyable listening experience than some of Tresor's more home listening-orientated releases, such as Headquarters or some of the latter volumes in their popular series of numbered compilations. Where these albums sometimes tend to get a bit too mid-tempo and experimental for their own good, the tracks on Annex 2 stay true to an aesthetic based primarily on rhythm. So while songs such as the Advent's "Sound Sketches 3" and Leo Laker's "Our Times" never seem to drift very far away from their minimal techno motifs, looped percussive rhythms, and fast tempos, they are quite capable of evoking a high sense of energy. In addition, there are a good number of non-DJ-friendly tracks here, such as Juan Atkins' techno meets vocal pop song, "Never Tempt Me," and the down-tempo chill out vibes of Savvas Ysatis' "Alright." These sorts of tracks help break up the minimal dancefloor techno of the aforementioned style of tracks, integrating an always welcome sense of variety that was sorely lacking on some of Tresor's compilations from this same time period -- Tresor 5 and Headquarters. In fact, though one might think of this album as a spotty collection of B-sides and outtakes, given the concept of the album, Annex 2 surprisingly stands beside Tresor's numbered series; for what it lacks in quality at certain points, it compensates with a well-laid out track selection focused on variety.
