about Max, maybe money talks(or create commentary), dog barks. :))
this video, it was not an offense ofc. Bjorn has used well known techniques(nothing magic like how to use subconscious beats in trance music like things :) ) so it's an intermediate,
in expert level I'm really curious thinks(the background) like mode changes for ex. Arty in Rush uses Eb major scale with F tonal center(2nd scale degree) which is F Dorian mode except in the break/chorus where it has been changed to Eb(1st scale degree) Ionian(major) mode (and he uses mode changes in all of his songs), so a tutorial about the mode changes would be nice :)
or how to create secondary etc.melodies using counterpoint techniques so series about not just the "basic" well known things like how to set eq/compressor/reverb/DAW routing ones
or an expert series about tension building http://edmprod.com/tension/ there are so many exciting topic in trance :))
