bufo marinus is the biological name of the cane toad. i have a rainforest cd where these cane toads just sing two notes. im playing 2 notes too on din, Robert Atwood is on Variseq, Geraldine McEwan on Violin and Evan Raskob on Djembe and Ukelele.
This is a short tune I created based on an indian music raga called malkauns. I perform live on my own software musical instrument called din [free software, more info: http://code.google.com/p/din ]. Better listened on loudspeakers than headphones.
