The Green Pajamas: Seven Fathoms Down and Falling (1999)
Although they have a number of really good albums, few quite make it to greatness, each offering a few terrific tunes making them better suited for an outstanding home-made compilation. This one may be the best stand-alone album, if only because it's got their greatest moment, the deliriously heart-warming love song "She's Still Bewitching Me." It's a haunting (literally), jangly pop delight, begging to be included on every mixtape you'll ever make.
Other highlights include opening track "Just A Breath Away," with its buzzing psychedelic guitar sounds; the folk-psych "My Visit With Magpie," sounding like the Strawbs crossed with late-period XTC/Dukes of Stratosphear; the insistent and catchy "Bronte Moon"; and the Beatlesque psychedelia of "Planet Love." Overall it's a great introduction to an unjustly overlooked band; but they have a ton of great music, and you could spend hours just getting lost in their Spotify page. There's also a decent career overview (Through Glass Colored Roses), though I find the selections diverge significantly from my home-brewed mix.
