It doesn’t get brought up as much as some other pleasures in music, but it really is a wonderful thing to see a new label hitting the ground running. Vesperian has already caught my firm attention this year, facilitating some excellent symphonic black metal by way of Stormkeep and some sublime Western gothic darkness from Dry Wedding. Of course, Wayfarer and Dreadnought are both ahead promising further atmospheric marvels. But hey, not all atmosphere has to come from metal bands, right? And surely not all of it has to lean on darker moods?
Well, once again, Vesperian has a band for us. Finland’s Polymoon is here to deliver a psychedelic wash of warm, fuzzy feelings and uplifting energy across their third album Mariposa Magic! (gotta love a band excited enough to put an exclamation point in the title). Now, Finnish psychedelia isn’t a territory I’m totally unfamiliar with. Of course I love the perpetual blackened bad trip of Oranssi Pazuzu, and I’ve also had my fun dabbling in the likes of Circle and Pharaoh Overlord. Mariposa Magic! specifically exist as a near opposite of that former band, channeling a similar instrumental setup into an extremely lush and genuinely pretty kaleidoscope of sound.
Emerging like a cocooned butterfly (heh) from the glistening radiance that opens “Ultra Bloom”, Polymoon spreads its wings into a vibrant swirl of trippy shoegaze-influenced energy, feeling positively alive in its swells and relaxations. The guitar work from Jesse Jaksola and Otto Kontio doesn’t lean on being too flashy, aiming to create a technicolor whirlpool of entrancing chords or more energetic riffing while the former’s glistening synths tends to take the lead. The following “I End, You Begin” flips the script with a much more motorik krautrock vibe, powered along by the insistent rhythm section of Tuomas Heikura (drums) and Marco Menestrina (bass).
One element of Mariposa Magic! that I found particularly endearing was Polymoon‘s latent sense of prog rock adventurism. The vocal lines and verse rhythms of “Lost in Sound, Found in Color” wind around with a complexity that Yes could have woven into one of their 70’s albums. That band’s same sort of cosmic optimism could likewise be found in the grand hooks of “Welcome to Another Dimension”, before the wonderful exercise in peaks and valleys that is “Glass House, Mortal Rooms”. The energetic thrust that kicks off the song is excellent, while that quieter interlude in the center is just plain beautiful (similar stretches of relatively empty space also underpin “Velvet Rain”).
And since I haven’t mentioned him as of yet, it has to be said that Kalle-Erik Kosonen has a practically perfect voice for this kind of psychedelic rock. His range is wide and capable, but never feels forced or aggressive at any point. The moments of harmony that build up on some tracks are borderline enrapturing, and alongside the grand production, Mariposa Magic! is practically flawless in terms of presentation. The only real gripe one could try to make is that on an individual song basis, the band isn’t aiming to make the most memorable individual tracks. Polymoon is the kind of band that crafts vibes much more so than direct songs, so picking singles or highlights is a bit of a crapshoot that depends on the listener’s mood.
But when it comes down to it, Mariposa Magic! is the kind of album that’s meant to be heard as a whole. And when you do give the album that time and attention, it is absolutely hypnotic in its colorful wash of space rock delight. Polymoon has delivered the sort of album that can’t fail to put you in a freer, brighter, and a bit trippier headspace when you settle into it, and it’s also the sort of album that’ll send me running to their back catalog for another hit of the good stuff. Far out, man.
