There is a real musical talent in writing, performing, recording, arranging, producing, mixing and mastering music, so much that traditional musicians will pay thousands for those services. Yet, they don't seem to rate them as musical skills in the same way. It is bullshit honestly.

Hahaha, LOVE this! I think you are right (note: am not a DJ, not a producer, not an artist of any kind, but just a big electronic music fan :)). I agree, electronic music producers do a lot of things themselves, others with more 'classical' instruments pay big dollars for.

Just because some guitar playing is more easily understood as being musical than let's say, a full live set using a grid based Monome using a custom Max/MSP code doesn't make it less of a musical skill.

Actually, I would argue the artist bringing a good live act has more skills than the guitar player. Try and bring an audience into a flow for an hour with just a guitar.
