In case you don’t know about OK go ( where have you been?) They are a band who hail, for the most part, from Chicago, USA. They consist of Damian Kulash ( lead vocals and guitar), Tim Nordwind(Bass and Vocals), Dan Konopka(drums & percussion), Andy Ross (guitar, keyboards,vocals) Andy joined in 2005 replacing Andy Duncan.
They are renowned for the elaborate videos which, to the best of my knowledge, are always shot in one take.
This was one of my early favourites.
This was also copied (very badly) by Berocca and used as their ad campaign.
I should have posted this ages ago but I am posting this now as they have a new single and equally great new video out. It is also an interactive experiment with Google chrome which is great.
