Okay, maybe not "great," but not as bad as I expected either.
From 1968, please enjoy The Boston Tea Party -- who were NOT in fact a part of the failed MGM Records Bosstown Sound hype (they were actually from Burbank California) -- and the opening track of their eponymous debut album, the "we hope you will enjoy the show"-starting garage psych anthem "I'm Telling You."
Interesting guitar solo, no? If interesting is precisely the right word.
In any case, I'm rather taken with the song's lyrics, which are as vintage a slice of "We're the young generation and we've got something to say" post-Monkees it's-what's-happening-baby rhetoric as has ever been heard by sentient mammalian ears. And a good thing, too, because as the late great Lester Bangs observed (in a review of early 70s glam rockers White Witch) the other default stance of the garage psychedelia moment was to give pimply male virgins the opportunity to sing about sex without (overtly) revealing their rank inexperience in that regard.
I should also add that the Tea Party can observed plying their trade in the 1969 trash biker flick classic The Cycle Savages with Bruce Dern, which behooves beholding.
