There must be so much recorded material from Journey right now off tours from '98 through '05.... I just don't see why whe don't have a full live record from the band since '98 (culled from the classic era anyway).
If you want to go a less expensive route, then do what Foreigner just did to get a live record out with their new lineup. A bare-bones "Extended Versions" through BMG. I can't believe there'd be any legalities that would preclude that, nor do I think the BMG, given that they embraced the the new Foreigner would turn journey away. You do that, you'd probably get a 10-song live album of the band covering classic material.
Or you put your own out through Sanctuary (?) or another label or through the site like they first did w/ Red13 and you can include Augie-era material... get through the atrophy, boyz.
