OK, not sure where exactly your musical tastes lie, so this might all sound elementary...If you liked the sound of Glen Campbell, try any 65-71 Beach Boys album. I like "Beach Boys Today" (IN MONO ONLY) or anything from "Pet Sounds" through "Surf's Up." Note that Pet Sounds should be mono, but all the ones after that are stereo. Simon & Garfunkel's "Bookends," any late 60s Merle Haggard, Elvis' "From Elvis In Memphis" and "Back In Memphis," Moby Grape's first LP (self-titled), and Spirit's "12 Dreams of Dr. Sardonicus" are all good. The Spirit album is a MONSTER. I found a copy that looked pretty beat up... well played but not abused. It was just a plain-jane, yellow label pressing on Epic, and that thing sounds INCREDIBLE. In a different vein, look for an original pressing of the Rolling Stones' "Let It Bleed." It rocks harder than "Beggar's Banquet," is less "produced" than "Sticky Fingers," and is more varied than "Exile On Main Street." You can tell a first pressing because the spindle hole will be slightly too small, and you'll have to nudge the disk down onto the platter. It should also have a poster (though if someone took that out and lost it years ago, you'd never know).
