Clash of Cultures 4: Vienna music I saw

• Going to a blues/rock show in Vienna with Pertti Nurmi of FMI and seeing a German rocker singing early rock and roll songs in a voice that you could have sworn was Elvis Presley.
  
• Same show, different performer: White guy singing black delta blues with an authentic sounding growl.
  
• Different show, way different band: kick-ass Austrian reggae-rock-rap band at the club Flex, down by the Danube River.
  
• German Queen tribute band
  
• Street artists doing dixie-style music
  
• Hyper street-musician/accordian-player making rock-and-roll poses while belting out opera-quality vocals that filled the walking plaza
