There's a thing I have noticed with the synth artists I have been discovering (Solar Fields, etc.), and that is that they couldn't give a flying fuck for the 3 minute radio-friendly song.... they are perfectly happy for the motif to build over 3, 6, or even 15 minutes, before 'something happens' and the melody develops. And I good with that. REALLY good with that.
One of the things the Muppet Show used to do was build a song from like one random muppet banging on a rock then another one would twang on a vine then another would hump a vacuum cleaner then another one would play his tonsils and before too long they had a jam going and then one by one by one they'd all drop off until it's a random muppet banging on a rock. It was fuckin' awesome. Toby Marks thought so, too, I guess, because that's pretty much every Banco de Gaia song.
