Holy, "Brick Wall", Batman! You have a couple of instruments that are being negatively effected by your two-bus or group limiter - try backing of on the input to that.
That being said, I like this tune - its sounds ballzy AND musically interesting. I like the use your synth percussion elements and use of panning - you're having fun with it.
Good singer - what language?

Ok, thanks, I'm going to try adjust. Maybe is too many compression on master bus.
I am pleased to your opinion!
It's Czech language (Czech Republic, Europe)

There is a European style of vocal - especially for women singers - where they sing quite "straight". Very melodious and pleasant - even over heavy tracks. Your singer does that here. As a North American -- I'm more interested in hearing her belt it out - like at around 2:50, and then the very end -- when she powers up with the heavy voice her timbre changes - the song gets much more aggressive - that's a sound I like vocally. For my ear she's sings "too nice". I like urgency not relaxed vocals in a heavy song. But I'm also very aware of the tradition of this - it's a Euro thing so you do what you think best.

Yes the Mix is a bit heavy - I'll let others speak to it more specifically - I also thought the guitars were a bit thin and distant in the mix - especially on the intro when they were on their own. They knitted in better when the band came in, but there was some pretty booming echo and boomy bass that jump forward while pushing the band back.

Sounds like you guys have lots of fun -- and cool to hear Czech music -- Kafka & Milan Kundera are two of my favorite writers.

Sounds good. There's alot of highs going on Cymbals, Snare, Guitars and Vocals that are all fighting for the same spot. As a result they get clouded it makes things fatiguing and as a result you want to turn it down a bit.

There's also a ton of compression going on.. Maybe you used a multiband compressor and cranked the highs? This also causes some fatigue at full listening volume.

Great band, solid performances, sounds like its tracked well. You can hear the nuances of the instruments in a spot that the compression isn't crushing it only a few times though. For my ears too much compression and highs.

What's your opinion of your mix/master? Sometimes when you go to do something it doesn't turn out just right.. Due to speakers or listening volume.. Or bands arguing about how loud something is compared to something else..

Thanks for your feedback and we are glad that you like our music. Here is a recording, taking into account your opinions, there's less limitation, less compression and some changes in the mix.

We are satisfied with the sound, but it is still only an amateur recording method ... so we recorded it somehow, somehow mixed up, somehow it sounds, but if it sounds good or bad, we can not judge very well ... sounds good for us, but it's very subjective.
