Danny ....all good points
Most of this type of music isn't created at all with arrangers...so here lies the difficulty recreating them... and adding the vocals is another story. But as an arranger player you sometimes might find yourself in a gig that turns into a situation that you would need some modern up to date Hi Energy house music for dancing...here lies using alternatives like mp3's etc etc....which is just another tool for the player to make a successful affair.
