A really amazing collection of photos at Wolfgangs Vault in the photo section. If you've never been to the site, it's a must! Loads of really vintage photos (which are a little pricey) and live shows to stream from the concert vault - or buy (at a reasonable cost). And not of only Fleetwood Mac, but pretty much every band to come along since the 60's & 70's. Just a great site all around. You'll learn a lot and hear alot!
I noticed they've added more photos to the site since the last time I visited, which was sometime ago... Fleetwood Mac in New Haven, CT - 1975 & 1979 at the Veterans Memorial Coliseum and Hartford, CT at the Civic Center - 1977. Here are just a sample... There's more at the site.
Photographer, Joe Sia, captured moments by focusing on the faces of the performers, the crowd, and by giving the background, whether simple or wild, the importance it deserved in defining the artist and event.
