Practice loud with a good sound at least some of the time; you will never be able to play loud with a good sound if you never practice it. FWIW, the rest of the group should be encouraged to play with a full sound, using lots of air (I love telling my high school students to "Breathe my pasty friend, Breathe!" like the lozenges commercials.) Unfortunately, it may not be your place to do so. I am lucky to have two good and experienced BD's to be teaching under, who also respect me as a player. (The fact that I am around their age doesn't hurt, either.) While setting certain limits, they give me a fair amount of freedom to work within.
