I recommended that album for a reason. I was born and raised in Portugal before leaving to the UK and then the US. Fado and the Portuguese guitar it relies on are deeply based on the music of
Al-Andalus, the Muslim kingdoms that ruled much of the Iberian Peninsula for seven centuries. That's why the album hangs together so well, there's a wonderful continuum between North African, Portuguese, Spanish, and Sephardic music and poetry. Jordi Savall has also explored that territory often, for example in
Granada 1013-1526. Or Romina Basso in
Voces de Sefarad. For a great history of how it all came about, I love María Rosa Menocal's
The Ornament of the World. (I just found out there was a PBS special based on the book, available on iTunes or Amazon, planning to check it out).
