Now that I have a reasonable competence in recording and production with Logic and MIDI gear I want to focus on my playing and musicianship. I also want to learn more about 'mastering' etc. Some materials I have been considering are: Dick Grove's Musicianship course 1 'see it, hear it, play it' $820US Mastering Audio by Bob Katz $40ish US Hearing and Writing Music by Ron Gorow $40ish US What music related materials do you other LUGers recommend from positive personal experience?
