This 'free gig' RAtM are promising to play, how's that going to work then?
Here are just some of the things a promoter has to pay for:
venue, equipment hire, staff (sound engineer(s), lighting engineers, bouncers, ticketing staff) catering - feeding and watering the band and crew, accommodation, advertising, any visas/ licenses required, travel for band and crew.
If the venue is a field, you can add stage hire, rig hire, transport costs, toilet facilities, licensing, even MORE staff, parking facilities, camping facilities, temporary fencing, policing costs.
Who's footing that bill then? Don't see it being the record company - they can't wring out even more publicity from this, can they? Unless the band are footing the bill and covering the cost with paying dates (HA! who's going to pay to see a band when they can see them for free?) and/ or a new album, it's going to be CORPORATE sponsorship, I would guess.
Unless they do a free festival, and every band on before them pays on to cover costs...
But hey, let's not let the realities of the modern music industry spoil this magnanimous gesture :/
