I've previously mentioned Brady Rymer's blog, which, though updated only sporadically, is a fun read. There are a few other musician-authored blogs I've been reading for weeks if not months now, and I've been failing in my kids-music-news duties by not mentioning them before.
The best kids' musician-penned blog I know of is Monty Harper's blog, which includes links to his podcasts and gives some insight into the working world of a kids' musician. Harper's good humor, noticeable in his songs, is evident here, too.
A couple other artists who have more recently started blogging, of a sort, are Eric Herman and Yosi. Both take a slightly different approach from Rymer and Harper -- they've focused (thus far) on other kids' music artists. Herman's blog talks generally about assorted kids' artists, both well-known (Ralph's World) and not, and why he's enjoyed them. Yosi's blog focuses more on specific albums that he reviewed for a parenting magazine in New Jersey.
Harper has been blogging for a while now (longer than this site, even), so he understands what it takes to write a blog on an ongoing basis. We'll see whether Rymer, Herman, and Yosi want to keep it up. (And believe me, after that initial burst of expression, it's easy to let the blog just die a slow, painful death.)
Now there are other ways to communicate with fans -- Justin Roberts is a fairly regular newsletter publisher, for example, and Dan Zanes' newsletters, while not as regular, always have a nugget or two of good (or fun or useless, or all three) info. And Myspace, of course, has its own blogging capabilities. But I'm actually surprised that more artists haven't plunged into the blogosphere. It does seem to me a fairly cheap and easy way to establish connections between the artist and the audience, especially one that may be growing, at least in terms of the ability of an artist to reach a national audience. Monty, Eric, Yosi, Brady -- has it helped? Or is it a useless, time-consuming pain in the rear?
