Previous Albums


Contemporary music, early music, world music and classical music works. Click here to see all previous releases.

In the third volume of “The Songbook of Tchinar” series, Esin Yardimli Alves Pereira invites the audience to scare the death off its bones with a fierce dance tune, and plays through lament and hope in a heartwarming ballad.

The sixth album by the TWB Ensemble (The Wandering Bard) is an exhilarating journey through sound, a musical marvel that breathes new life into the medieval Cantigas de Santa Maria, attributed to Alfonso X, the Wise, a visionary Iberian king of the 13th century embellished by a legend from Leyriath.

You are a musician. So you do what you know the best. You start playing…
