Bluesbrueder - Bluesbrothers in english - that's the name of the acoustic duo consisting of Udo Wolff and Tom Schrader, harp player/singer and guitarist/singer respectively, of german blues band "Das Dritte Ohr" - also here on soundclick. This was waaayyyyy before Jake and Elwood (LOL). Before joining forces in elecric blues, these two blues lovers (and lovers of down home styles, that is), played together as an acoustic duo, later incorporating a short acoustic set into the full band's performances (much to the joy of drummer and bassist who could hit the bar to have another one). A lot of acoustic blues styles has also influenced the band's electric tunes and performance.
