Well, it depends on your INTENTION in the use of the "New Bay" term. I've noticed that, for instance, in Country, some of the recent Country music (i.e. Shania Twain, Faith Hill, Toby Keith, etc.) is often called "New Country." This wouldn't be so bad, but a lot of folks just use that label as an excuse to shut out any artist who made his/her debut before 2000. To them, if it ain't current, it's disposable. It's the whole "you can't join our club 'cause you're too old" mentality. For instance, my neighbor, who's a country freak, has a girlfriend who--you can mention Toby Keith or Shania Twain to her, and she'll smile, but you mention established artists like Willie Nelson, Johnny Cash (R.I.P.) or Waylon Jennings (for instance), and she'll turn her nose up and be like, "eeeeeeewww, that's old shit! It's so not what's happening, blah blah blah..." But these older Country artists should be shown the respect they deserve, IMHO, and shouldn't be shut out just to make room for the new. If an older artist continues to make great records, that person should still be recognized, even if said artist has been around awhile.
My point is, this "New Bay" term could end up doing the same. Fact: Many of the older artists are still making solid, dope, relevant music: Messy himself, San Quinn, Black C. (and his Right Way collegues), Yukmouth, JT and his Get Low associates (even though they've been quiet lately), Jay Tee and his 40 Ounce associates, Mac Dre and his folks (PSD, Dubee), and others. Even if they ARE "older" artists, it should be recognized that there IS still a place for them in today's Rap world ALONG WITH any new dope Bay artists that may blow up. And, like B-12 recently pointed out, a lot of old school Bay artists never really blew up outside the Bay as much as they could have during the '90s', so if they have a chance to sign w/ majors and FINALLY make it big, they deserve it as much as any "New Bay" artist, IMHO.
In other words, this "New Bay" label, if it sticks, should NOT be used as an excuse to shut Mess, Yuk, JT, Quinn, etc. out of the game by the Locksmiths, Balances, etc., so long as the older artists are still making dope records (which many are, IMHO). That's what labels like "New" and "Old" can do to music, if you let them. Just my opinion, though.
PEACE!
