dilettantism
"...Music isn't really like cooking--there's no reason why you can't have artists who make a whole dish out of the sonic equivalent of flour, or salt. (And you do--virtuosos of monochromatic concentration like Plastikman and Pole). And yet there's hardly any positive terms in pop critical discourse for fanatical focus or fixated perseverance... Look at dance magazines, and you will see reviews that approvingly list an artist's forays into genres other than the one whose section they are actually reviewed under. Stylistic inconstancy, generic treason, and dilettantism are, paradoxically, almost supreme values..."
