Been listening to their stuff for a while. Favourite song is without a doubt Nightcall. My main issue, and I think others felt this as well, was that there was a very similar tempo and structure to every song on the album. They start of slow and then get quite dancey towards the end. I don't know what made this particularly noticeable on If I Wait, but the iambic movement of every song gave the album a somewhat repetitive feeling. Have you heard VAULTS? Check out Premonitions. It's a tad darker than London Grammar without being as dark as Banks, for example. The singer's voice is also quite husky at times, it reminds me of the singer from a rock band called Dommin.
Yeah, I know it, but Kavinsky puts way too much synth into 'synthpop' for my liking. If you like both of these bands, maybe try out Polica? Lay Your Cards Out, Warrior Lord, and Wandering Star are good tracks with Smug from their most recent album Shulamith being my favourite. Sorry I'm not linking anything: I'm lazy and on mobile.
