I'd like to recommend a nice blog for fans of sleazy, high energy rock'n'roll:
If you have a band, you can announce your band free of charge to Spanish speaking audiences on both side of the Atlantic sea: Spain-in Europe, Argentina, Chile, Mexico, etc- in South America.
Just get in touch with Capitain Poon by clicking on "Cap Poon Myspace" section and go on to:
"If you believe that I can help to your band with a little bit of publicity, send your record, 10" or 7" at "capitainpoon.blogspot.com"."
Just as if you are a Rock'n'Roll music fan, you can get access to free promo & sample music tracks by going into "Comparte" link once you've entered a podcast.
Good luck! I hope for the best.
