From the name - and from the ad promising synthpop from "pioneers" - one would expect a shedload of classic early '80s synthpop.
And indeed, such there is. Human League, Heaven 17, OMD, Erasure, Yazoo, Pet Shop Boys, New Order, Joy Division, Gary Numan. Curiously no Depeche Mode (pity, it would be lovely to have Just Can't Get Enough in there and thus have three incarnations of Vince Clark; I suppose The Assembly would be too much to ask for...).
And many tracks by artists to whom history has been less kind, but the songs are no less good for that.
But then...there's also New Romantics (Duran Duran and Spandau Ballet both present and correct), New Wave (Blondie, not to mention Debbie Harry's French Kissin' in the USA), and even David Bowie gets a look in (Fashion), and other material that doesn't, by any reasonable standard, fit into the definition of "synthpop". I guess some of it is certainly early '80s enough to count as pioneering, but they're taking the p*ss with Johnny Hates Jazz's Shattered Dreams, surely?
OTOH, there are some lovely tracks in there which I've never had on CD before - Brilliant Mind by Furniture, Driving Away From Home by It's Immaterial...and heck, to be fair, Sigue Sigue Sputnik's Love Missile F1-11 is nowhere near as bad as I remembered, and probably does count as pioneering. Although on the basis they missed a trick by not including Big Audio Dynamite's E=MC2, which would have fitted perfectly amid some of the other material...
So yeah, there are some solid gems on there - amid a very few duff tracks - but they couldn't half do with being a bit tighter with the definitions.
