Renato Rozic and Raul sen Gupta play Bach - SEDNA .::. Dubrovnik Summer Festival Podcast #82

They indeed do play Bach.
Interesting part is that Renato plays electro-acoustic guitar, and Raul plays tabla (indian percussion instrument).

Do they play songs written by "Jazzy Jones aka Bach", or by Johann Sebastian Bach?

To find out all about this performance and also hear them you will need to watch this video podcast.

I will just tell you that composer is J.S. Bach, and that the  performance took place in Revelin fort in Dubrovnik at midnight on 7/16/2007
