I am a huge, huge Incubus fan. I was introduced to their music back during Morning View by my college room-mate and I have been hooked on ever since.
Anyway, I was watching Incubus covers on YouTube and I found several cover videos. I am no music expert but I reckon Incubus songs are pretty hard to cover. Nevertheless there are those who do great in covering some instruments.
But this guy I found is the only one who plays AND sings at the same time. Bravo, Bchew.
