Rough Guide addendum.
By the way, I'm about halfway done with the new Rough Guide to Tango (Second Edition), one of four new RGs I finally got to downloading a while back. Two thoughts. One, I need to listen to more tango. I've liked the Piazzolla I've heard and this comp is appealing on its surface, in a way that makes me think it would be pretty durable, and it sounds more recent--so the classic albums are probably really scrumptious. Two: all these RGs have bonus discs with one artist on them, and each time so far I figured I'd just turn it off when I was done, and each time I've wound up liking the single-artist disc. With Afrobeat Revival it was Kokolo; with Blues Revival, Samba Touré; with Gypsy Music (Second Ed.), Bela Lakatos & the Gypsy Youth Project. It seems like a combo of the RG series with the Introducing series World Music Network also does. Works nicely.
