Even in this crazy unpredictable world, some things are constant and guaranteed. One is cause and effect. Something happens, and because it does, a bunch of other stuff happens down the line, sometimes for the good of all involved.

For instance, years ago, Molly Rankin befriended next-door neighbor Kerri Maclellan, and as teenagers, the two buds from Cape Breton, Canada, discovered the sweet fuzz and jangle of '80s-era U.K. guitar pop -- an eternally pleasant sound that stands as one of life's other certainties. That caused them to form the band Alvvays, and that led to the brand-new video for the tune 'Adult Diversion' (watch it above), which now stands to make your Friday a whole lot brighter.

Alvvays are a young band, but they've already toured with the likes of Peter Bjorn and John and the Pains of Being Pure at Heart. The 'Adult Diversion' clip features Super 8 footage of the gang playing shows and chilling at the beach, and it appears on a single streaming on their website and due in stores early next year. Soon after, the group releases its debut, recorded at Yoko Eno Studio with Chad VanGaalen, and when that LP drops, expect the chain-reaction of pure-pop bliss to spread well beyond Canada.
