Who needs instruments when you have a backing track? God bless Logic.
Seriously, this is just karaoke.
Reminds me of when i was filming Caliban on a UK tour last year and during their soundcheck you could hear the amount of backing track they had. Needless to say the snotty UK hardcore kids were having none of it.
In stark contrast, Foals' cover of hollaback girl in the live lounge on the same episode sounds awesome.
