Ask Feligénio--he is on the case.
I've had the pleasure of many months of contact with Feligénio Medeiros: Açorean by birth, and a man with a voracious appetite for the fado. I first met him in person during a recent visit by the fadista Sonya da Silva to the US (see the post from this blog, with photos by Feligénio). This past month he brought Sara Correia from Lisbon to Massachusetts to perform in a variety of venues (report coming soon).
But his major contribution to the fado to date is his web site: FadoNight. The site is a collection of information on upcoming and prior fado shows, particularly the more intimate ones, that are happening in the US and Canada. The site also contains a large and ever-growing list of restaurants that offer fado.
This is an indispensable service to those (expecially in New England) who are looking for fado. The site is updated regularly. And if you know of some fado happening in the US that is not listed on the site, send him some email: info at fadonight dot com.
P.S. Feligénio and I are also both steady contributors to the group "Fado in the US" on Facebook, where you can go for additional background and reviews of fado shows in the US. The group is open. If you want to post, simply request permission to join.
