Apparently the rhythm guitarist is a little incognito...no credit caption & his face is almost always in the shadow of his hat brim, but with careful listening and a pre-hunch he might be a Weiss, could hear Eva Slongo introduce Robert Weiss...I think...
Wawau is playing a Gibson archtop here, but it doesn't matter what he plays - I like it.
Joel Locher on kontrabass needs no introduction.
There are a lot of excellent violinists out there, including, to my surprise, Bireli Lagrene. To me, Eva is one of the most artistic improvisers on violin I've heard. She's also the best looking one on the stage ;O).
