1)What?s wrong with "pretty polished pieces" or "clean songs"??
2)Have you ever heard to Ari Eisinger???. Extremely clean a a lot of expressive.
3)Why the blues (or ragtime) must sound "dirty" o full of "technical mistakes" ??
Hi Gustavo:
I'm speaking only for myself in answering your questions.
1) Absolutely nothing.
2) Sure I've heard of Ari. Check out the comments and review by our own Uncle Bud. IMHO Ari and his music is/are top shelf stuff, and I wouldn't want him to change a thing--except release more CDs.
3) Blues or ragtime doesn't have to sound dirty or full of technical mistakes.
My last comment in my post was meant to direct you toward the more percussive players and perhaps expand your playing so as to include some of their technique. It was just a suggestion, one that you do not have to follow. A few others are:
Find yourself and be yourself--musically and otherwise.
There are a couple of old sayings: "To each his/her own" and "Live and let live." Perhaps these can be modified to "To each his/her own music" and "Play and let play."
I hope the above serve to clarify my previous comments.
Regards,
Stuart
