Doctor Who's Blues?
Dr. Alexey Agranovsky, that's who! Biochemist by day, bluesman at night.
Frantic searching on the Internet the next day revealed that the singer/guitarist was Dr. Alexey Agranovsky of the band Chernyi Bhleb (Black Bread). Dr. Agranovsky has an infectious smile and looks like a cross between Barry Manilow and Dr Who:
The harp player appears to have been Alex Bratetsky, judging from the pictures on Agranovsky's web site. After some banter (in Russian) with the host of Born in the USSR and some phone calls from the audience, Agranovsky and Bratetsky played T. Bone Walker's classic "Stormy Monday Blues". Interestingly, Bratetsky played his harp into a tin cup!
Dr. Agranovsky has a good bit of music online. English is not his first language, but he has a warble in his voice that really hits the spot. All the songs are blues and in English, except for "Слишком поздно (Slishkom pozdno)", which is highlighted by some beautiful slide guitar.
Well worth a listen ... make that repeated listenings!
