If you're on Naxos' newsletter mailing list, you should have the free album download offer for May in your email inbox by now. I have no link to an URL to give you; you must access the offer from your email message.
The album is produced by a company called Orfeo*, which is a new one to me. The title of the album is Händel: Concerti grossi, Op. 6: Nos. 1, 6, 10, 12 • Das Alexanderfest.
You can get either the MP3 version of the album, or the FLAC version (is there really a choice here? ha)
Later in the month, we will get to choose one album free, from three choices. Actually, I think that I prefer this present giveaway, where we have one choice (well, I guess if there's just one of 'em, there's not a choice, then, is there? ha) giveaway even though we are limited to just one "choice" with this offer. With the second giveaway, I sometimes I spend an hour or more trying to decide which one of three albums that I want; with this one, the "choice" is made for me.
This free offer is good "until" May 31, 2017. My advice: go ahead and download it now, so you don't forget about it.
If you are not a subscriber to Naxo's newsletter, you can sign up at the bottom of
their homepage.
* I just found out that it is a German company (URL:
