Internet broadcasting of musical events brings its own challenges, but is also tremendously rewarding when it's done well. When running our own web tv show Nexuslive a few years ago we operated twin desks with seperate mixes for the room and for the web just to get the sound perfect.
As well as running live webcasts of massive events such as Edinburgh's Hogmanay, we also host on demand media for a number of artists.
We hosted all video media for The Killers just as the world began to get excited by them. (that .. was .. crazy)
