As a 60's fan, I always look for obscure rock albums from that time, and of course sometimes one can meet with records that turn out to suck. However, that seeking can also bring rewards like finding really good obscure albums. The following albums are some examples, which I recommend you to listen to if you didn't.
The United States Of America (1968). The only album by the band of the same name, it's an amazing rarety. Very experimental but still fun. As a curious detail, there's no guitar in the record, but it's replaced by other electric instruments and sounds so that you won't notice it. Highlights include "Hard Coming Love", "The Garden Of Earthly Delights", "Where Is Yesterday" and the funny Kinks-influenced "I Won't Leave My Wooden Wife For You, Sugar".
Nazz (1968). The debut album of the same named band, commanded by a teenager Todd Rundgren. The sound is not very original, it's mostly a rip-off of other 60's acts, but if you like bands like Cream, the Yardbirds (actually the name of the band came from their song "The Nazz Are Blue") and the Who (the album even starts with the same intro of "I Can't Explain") you will enjoy it a lot. The best songs are the great opener "Open My Eyes" and the magnificent ballad "Hello, It's Me", but the whole record is worth to be heard.
Love - Four Sail (1969). Love is now a relatively well known band, especially because of their cult album
Forever Changes. However,
Four Sail seems to be ignored even by rock critics, and one can understand why: at this point only Arthur Lee stayed from the original lineup of the band. But the record itself is really good. The sound is wilder than the three classic albums of the band, with several acid rockers that seem to be inspired by Cream and Hendrix ("August"; "Singing Cowboy"; "Robert Montgomery"), but there was also space for a gentle tune that would have fit in fine on
Forever Changes ("Always See Your Face").
Now you can recommend other obscure 60's records that I might not have heard.
