Word of advice for attending shows at Luther's Blues: bring a sweater. I've gone to two shows there and it was freezing both times. Nice atmosphere otherwise.
The Nields were great, as usual. The show was a little shorter than I am accustomed to, but I imagine that was because there was a second show taking place later that night—Marques Bovre and the Evil Twins are playing their last show tonight at 10 (looks at watch....started about 15 minutes ago), featuring the return of Linus. So, the Nields couldn't linger. Neither could their fans, as the staff cleared the room immediately post-show. There was quite a line outside waiting to get in.
I think I'd perfer to see the Nields at the Pres House. It seems a more friendly venue for the folkie crowd.
