I doubt the Bose is a viable option in France but have not checked.

There are 2 basic ways of using Band in a Box in public performance.

The first is to use a computer running Band in a Box with line out to a mixer and both the computer sounds and the guitar sounds are mixed and go to an amplifier. You need some sort of stand for the laptop. If you are going to sing you need a mic. So you need at least a 4 channel mixer. Next you decide on a powered mixer to speakers. Do you need the speakers on poles? That depends on the size of the venue. You can have non powered speakers with a powered mixer. You can have a non-powered mixer with powered speakers.

The second type of method uses all the above without the computer. You make 'backing' tracks and use a player, like an mp3 player or similar, to make the sounds NOT the computer at the venue.

Behringer, being a maker of a lot of gear in Europe, should be available at your local places selling or renting gear. My advice would be to talk with them. Find out if you can rent gear. My first setep was a rented Fender system with 2 speakers attached to the amp that looked like a bullet. I paid per month and after 3 years owned it.

A quelle lieu exactement? Je serais a Pas de Calais et les environs le 3 ~ 6 mai.
