I liked the first Stills album ok but I'm really digging 'Without Feathers.' The first had a couple of great songs but I think this one is good all the way through.
I thought both bands were really solid live. Rogue Wave didn't do anything overly special but you can't get much better for an opening band.
The Stills were really good, lots of energy, good banter, etc. The two lead guys trade vocals which is cool and changes things up a bit from one song to the next.
My only real complaint was that they played 3 or 4 of their better songs (at least the ones I like) right off the bat and as a result the encore was fairly weak. They played the French song from the first album and another song that I consider one of their throw-aways. All in all, a very solid performance and definitely worth the $12 I paid.
A couple of others chimed in here:
