I don't hear Yes here, nor Jon Anderson except for a couple of Yes common places thrown in, especially in last song. Let's say one minute in the whole EP.
Maybe because I listened a lot to Yes (I'm 44), I know every album note by note and melodies are quite different from the ones by these guys. But I respect people's thinking, and same time I can't lie to avoid somebody get offended (I'm sorry, if it happens).
So If they didn't mention Yes singer in last song I didn't even notice it.
Both music and vocals remind me A LOT moe. and Umphrey's McGee. Lead singer seem Brendan Bayliss of Umphrey's McGee; when they sing in chorus they sound more like the three singers in moe.
My favorite song is Soldier... which remind me Anchor Drops by Umphrey McGee.
But they are not a clone of these band, simply they are not progressive, but a jam band, and very interesting I have to say. Jam bands sound similar as they play at high technical level, and they make arena rock mixed with progressive and fusion. It's a very recognizable formula (like 80s californian hardcore punx, to make an example) so can push all the band in the genre to sound similar (if listened to with distraction).
Here they miss the "great shot", but I'm sure next record they'll find a majestic series of hooks, You can perceive they are on the go, they're looking for THE solution. I think this band got numbers, and they can express a wide range of styles, by now they are in a kind of funnel, so songs sound like a single song splitted by three.
