I fancy a well-made mix tape; I just think there's too many people involved in them. The music, that is. I never understood the whole alias/pseudonym thing that's adopted, especially in electronic dance music, to make something in a different style. That sounds like cowardice. Well, I understand apprehensions about prejudice, a la "If they see my name attached, they won't listen" and I'm always one for a pleasant surprise. I also know some producers adopt other names to escape contractual obligations. (Fact: humans are the only species to lay claim to a series of squiggly shapes.) But too often, it doesn't serve a useful purpose, and just confuses the heck out of would-be listeners. There are already too many different people who sound alike. (Exhibit A: trance sub-anthems.)
I'd like to see someONE release a mix album that they completely did (for all effective purposes outside of session players, a collaboration or two, and post-production) and each track could be under a different alias. They wouldn't reveal this until sometime later to collect listeners' reactions — there could be clues in the track titles — and they'd genuinely have to be able to shift into different psych states and produce work which is really not like their "usual" self. Bonus points if they're comparatively unknown to begin with. That way, it elegantly resolves the tension of "Are they the same?" and collects it all in a unified release, instead of scattering singles about.
For that matter, there aren't enough obscure experimental artists who daylight as big pop stars. It'd be discovered too easily but I think brilliance just can't be blinded by boxes, yeah…
