Thanks a lot, man! Glad you liked it!
If you include recording audio too it depends on how long it takes me to learn and polish the song, but for this one I think that it took me 2 days and a half to learn the song, record a demo, shoot and edit the video, re-record all the instruments and vocals and edit, mix and master it.
I have a Shure SM7B, but I think that a handheld mic is more dynamic than a stand mic, more if I´m not able to play guitar and sing this song (it´s fast and I even made it faster, and has all those palm mutes...James' habillity to sing and play guitar is amazing)
