I just saw Ani DiFranco do a short guest-shot on the morning news program. They let her sing a song and promised to let her do another later. But while watching her play, I noticed all her right hand fingers had something black on them, all the way to, like the second knuckles. I know this has to be some kind of fingerpick, but I've never seen one so huge. How do you feel the strings? How do you even keep the things on? I'm thinking they look like a black 1 1/2"" sleeve on the end of each finger. She does have a very percussive attack, but simple fake nails would give her just as much. I'm confused by this. Does anybody know what this product is? Are they worth it to try out? Or are they like the Tony Levin Funk Fingers I bought several years ago...great for Tony, useless for me.
