OK It could be revivel but this old "Canterbury" sound is still an original one. If I can explain with emotional words I call it "gentle progressiv rock".
Anyway call it as you want but this sound is part of late '70 music history.

I post this today because in October there is a life show of The Dream Syndicate here in Italy (I think is a reunion but I am not so informed about the actual composition of the band.
I have not yet decided if I will go or if it is better to listen to the original version of 1982 (I have the vinyl version of the front picture here). In the link there is a reissue version with more tracks.
