Honestly, I've given SuperImposer a listen and I'm still not too sold. I don't like the vocals, and there's nothing that really sticks out musically. They're lots of good riffs, but nothing great.
Maybe Heaven Alive is the form of Oceansize that'd be up my street. I dunno. It's the only time I've listened to them and gone "oh that's a fantastic melody." The rest isn't really THAT melodic. It's just sort of rhythmic. And they're good rhythms! But the music doesn't enchant me, which is a bit disappointing after so many good reviews. I'll give 'em a few more chances, but I'm not holding my breath, tbh.
Still, I like their attitude to music and their, er, relationship with their fans? I think it's quite healthy. They've got a lot of personality, which I really dig.
