Good job on the kalimba, plat. I can tell you've been practicing and were pretty confident in your ability to nail that melody on command. Otherwise, you wouldn't have recorded that long intro at the beginning. It would've been annoying to read that whole intro, flub the melody, and then have to start over and read that long, boring intro again.
Man, this gives me flashbacks of my time at Disney trying to be as "African" as possible and wandering around with one of these, ambushing tourists with my wicked stylings.
I think in my 24 years of living in Africa I saw maybe one of them. Good old Disney.
I listened to both of these. Will be interesting to check back in the future, to see how far you have gotten with this. Maybe you can play Boom's parts for Pearl Jam.
