Black Forest/Black Sea is the duo of Jeffrey Alexander and Miriam Goldberg. They play free-form music that draws from folk traditions. They formed the band in April of 2003 in Providence, RI. In January 2008, they relocated to Pittsburgh, PA. Miriam primarily plays cello and sings, while Jeffrey primarily plays guitar, although both also employ various electronics, omnichord, live sampling tools, strumstick, and whatever they can get their hands on. Since forming, they have toured extensively in the US and Europe, from Savonlinna to Sicily, Riga to Reykjavik and Portland to Portland, performing more than 200 concerts in 18 different countries.

BF/BS have toured with Fursaxa, Christina Carter (of Scorces, Charalambides), Gravenhurst and in Poland with the Magic Carpathian Project. They have also collaborated on recordings with Kemialliset Ystavat from Finland, Fursaxa, Christina Carter, Glenn Donaldson (of the Jewelled Antler Collective), Gravenhurst from the UK, ES from Finland, Stefano Pilia from Italy and German psych-folk duo Fit and Limo.

Before forming this new project, both Jeffrey and Miriam were members of the acid-folk group Iditarod (1996-2003). the Iditarod (BlueSanct / Secretly Canadian, Elsie and Jack, Time-Lag and Camera Obscura labels) toured extensively in the USA, Canada, and Europe and have been featured repeatedly in magazines like the Wire, Broken Face, Mojo, Rockerilla, Copper Press, Magnet, Dream Magazine, Ptolemaic Terrascope and Rolling Stone. They performed at the 5th Terrastock Festival in Boston, where a 5x7" box-set was released featuring the Iditarod, Sonic Youth, Bardo Pond, Stone Breath and Charalambides. BF/BS also operate the SECRET EYE record label and they solely organized the TERRASTOCK SIX festival, as well.
