The guitar wizards from Jefferson Airplane (Jorma Kaukonen and Jack Casady) used their spin-off act initially to debut their love of acoustic country blues numbers. A very low-key, scholarly document.

This came out only two years after their original run as a band, yet generally they sound like a grizzled and faded version of their former selves. Almost as if they aged prematurely. Somehow, the oddities remain – witness "Chinese Song". This is definitely not for everyone but if you've got this far with the Grape, you might as well spin this once or twice.

It's likeable and coy and all that but hope? Are you kidding me? We're long past that point with these guys. Small wonder it was the last record of the group's original run.

Blue Cheer pretty much try anything and everything on this release, even a meditative sitar jam buffeted by peppy synthesizer playing ("Babaji (Twilight Raga)"). The weird thing is, it's easily their least memorable effort to date. But the effort was admirable, at least.

Well, here's a change – Santana goes the jazz fusion route. Which kind of made sense since, at the same time, it was beginning to become a big thing in serious music circles. But then again, didn't they have a really good fusion thing going in the first place? Other than some guitar heroics from Carlos, this record is rather forgettable.
