There are quite a few artists who's music isn't necessarily labeled as 'trance' per se, but which has all the ingredients of Trance music when you actually listen to it. Maybe a little slower and more chilled but non-the-less still music that trances you out. You could call some of this 'proto-trance', that"s what I have some of this stuff labelled as in my iTunes library. Essentially some of these tunes are from a time before trance really started to take off as a genre in and of itself.
On this blog I mostly stick to old school tuneage (records), mainly stuff from '87 to '99, so having said that below are a few tunes that aren't necessarily trance but definitely have a trance feel to them.
BBG Snappiness - (Sweet Instrumental) (1990)
Drum Club – Follow The Sun (1993)
I did want to post the version from their Live In Iceland CD but couldn't find any uploads on youtube so we'll have to make do with this version.
Orbital - Halcyon + On + On (1993)
I'm sure everyone knows this one, but what the hell...
