I've been away from the one-man-bands for a while but this one was easy as it was sent straight into my inbox. One Hand Man's Band is a one-man-band from Spain, playing serious punk-blues. (By the way, do not confuse this act with One Man Hand, which is a one-man-band from Portugal). This guy reminds me a little bit of Jawbone. Good stuff.
This is him live in January of this year
And this is in June of 2010 in Madrid
