OK
This one was invented by my current in house engineer and he puts it to good use.
Senario - Rock band wants to greedily go for too many tracks in too short a space of time (a common situation for us)
Solution - Rather than be driven into the ground and forced to work 18 hour days.. Suggest that you put down 4 basic live tracks tracks but only take 2 or 3 of them on to the 'overdub & mix' stage.
Result - studio timetable isn't ruined by engineer needing a weeks sleep to recover from a two day session, clients not leaving with poor mixes with stupid late night mistakes like tambourines WAY too loud.. Clients leave with good sounding work and come back when they can afford it to complete the overdubs & mix on the other songs.
