Title: Mala Vida
Artist: Mano Negra
Album: Patchanka
Year: 1988

I think the first part of Riff 1 is too high, he might use a 5-string bass guitar, or 
his guitar in drop D - but this sounds fun too! :-)

Just listen to the song when to use which riff - the third riff is easy to hear as the 
is the same as the guitar riff.
Have fun!
