'Mysterious Traveller' is not so much an album as a back catalogue documenting a decade long, occasional collaboration between the UK electronic duo, System 7, and techno pioneer Derrick May.
Apart from the other qualities contained here, this is definitely one for the boffins, containing such rare gems as the Mayday mix of 'Altitude' and never before released material such as 'Big Sky City - Above The Clouds mix'.
The title track, 'Mysterious Traveller', appears twice in the set, making its debut in its new 'Groovy In Tent mix', an epic slab of noodling but expertly rendered tech funk.
The original May mix of 'Big City Sky' is also included. A master piece in its own right, it builds from long spluttering drum lines before swelling to it's full blown emotion wrenching glory.
May's Rhythim is Rhythim moniker appears on the 'Icon-Montage mix', while System 7 go it alone with the debut release of 'E-Merge'. Other new material comes in the form of the recently completed 'Prototype' - originally recorded by May and System 7 in 1990 but only finished this year.
This, like most of the tracks included here, has had to travel a long way. But it's all still remarkably fresh on arrival.
