Why doesn't ska get more respect?
I say it has less to do with a lack of socially-conscious bands and more to do with depth of craftsmanship, and breadth of inspiration.
Justin from Mrs. Skannotto told me about going back to his classical training to stay grounded, because he would pick up bad habits working with amplification, and that started the gears turning.
To a classical or jazz player, ska probably sounds rough, shallow and immature.
Punk rebelled against technically sound but overly sanitized music. We now see the opposite problem, going from over-cerebral, antiseptic performances to a consistently raw, unrefined sound with the barest grasp of technique. The immediate results may be pleasing, but the musician's development is stunted, restricted to a shallow pool of options.
Inbreeding is everywhere. Emo might have some redeeming qualities, but I find the "emo vocal style" too off-putting to contemplate it. One, the sound is annoying. Two, why the hell do so many of them sound alike?
Play Devil's Advocate and look at ska. People complain that all ska bands sound alike, and there is a certain grain of truth to this. I struggle to differentiate even quality bands. Too many musicians grew up listening to a narrow range of genres and dreamed of being the next Reel Big Fish (grew up on nu-metal and dreamed of being the next Slipknot or whatever. I'm picking on genres, not specific bands.)
Musicians, a challenge: you want respect?
Practice more, take lessons, listen to genres outside your comfort zone.
That's all.
