From the listing:
Mostly Autumn -- one of our friends here has been posting links to this band
Anekdoten -- From Sweden, the band was inspired by King Crimson. It's first 4 albums (from 1993 to 2003) are all excellent, and were near the top of many progressive lists.
Lucifer's Friend -- Usually associated with the heavies (DP/BS/UH/LZ for example), this German band was an oddity in itself ... they could not sell at home, but in Chicago ... they sold really well! What does Chicago know about music that we don't?
Spock's Beard -- Band from LA that has been on the top of many progressive lists for a few years, and their best time was between 1995 and 2005. Very impressive band, specially with Neal Morse in those early days.
RPWL -- Was a Pink Floyd like band, and did a lot of PF material in the early days.
Focus -- Without Jan Akkerman these days and run by Thiijs Van Leer ... But a show this big, I think that Jan might just show up if he is not ill.
Jane -- German band with a very nice set of albums in the 70's that is finding a nice resurgence these days.
Hawkwind -- Ever the saga, with changes and that, it seems that this time around they still have Tim Blake and a couple of the same folks for a few years ... that makes them even better on stage, and they already are very good on stage anyway. Not sure I want to hear "Masters of the Universe" yet again, but I figure Strummy will love to rock out on it!
Magic Pie -- Recently mentioned on the listens here on the board. Very nice stuff.
Carl Palmer's -- Do not know much about it, but not surprised, although this may be now a sort of tribute, and I think it will be emotional as all heck!
The Musical Box -- The one and only Genesis material band, other than Steve Hackett. They are actually very tight and good, and enjoyable, and do albums in their entirety. Looks like they will do "Foxtrot".
These are the only ones I know ... right now. Looking and listening to the others right now, as soon as I can get a spreadsheet finished for Space Pirate Radio ... had mistakes and missing stuff for 1976 and 1977 that I am listening to again. Only about 80 to 90 hours of listening ... can't stop a piece of music or event, now, can we?
