I liked the song, but what is he really doing live? Isn't the music sequenced before the show? Or is he inputting some parameters on the fly? (I don't know what software options are available for the GB...)
I like to write music for my cassette tapes. I then stand on street corners and play them through a boom box. The most difficult part of playing live is having to pretend to press the buttons on the boombox so it looks like I'm playing. Sometimes I even wave my arms in the air, as if summoning music from the heavens. Thankfully the audience don't know that it's coming from a rather more down to earth cassette tape.
When I went to japan I saw this backpack that was speakers. that's right, a ghttoblasting, speakers backpack! that would be great for busking hh? JVC i think.
anyway this clip exposes the bondary that this guys pushing in terms of live performance. Beyong start / stop, wave your arms there's not too much you can do i spose. now if he had a coupla more boxes wouldn't that be better? tweak them, fx them?
