Muse.

Both Madrid and Barcelona are great.

I'm lucky, i attended a few concerts in my life, and from tiny bar to olympic stadiums, bands like Arctic Monkeys, Mumford and Sons, giants like Coldplay, Green Day, Depeche Mode, Biffy Clyro, but Muse it's bigger, better, it's huge, in all sense, their music, so complex and well played, they really play music, great guitar solos, beautiful pieces of piano, electric and solid bass and tough drums and an enourmous voice....

Let me show a few examples
Example 1

Example 2

rest my case

I've seen a ton of concerts..

For the best, i'd choose probably Foo Fighters (sooo intense).

Muse is a close 2nd and there's also Kaiser Chiefs which i loved. Also saw MCR a "few" days before the break up, and that is very special to me.

Imagine Dragons at Optimus Alive in Portugal.
Those guys are beasts on stage

Rammstein, Phoenix, Arizona, 2012. In the pit. Most badass concert ever, it was so much fun.

Hedley (my favorite band so far), I was so excited to see them.
Others: Enter Shikari, Bring Me The Horizon, Oedipis, Kaiser Chiefs, Limp Bizkit and Anthrax.

Savant was my favorite. Got to meet him outside after the show, he hung around, took a couple pictures with us, and taught us some stuff about music production on the spot! It was really awesome. The other bands worth mentioning that I got to meet after the awesome shows are: 3 Inches of Blood, Magnus Rising, and All Else Fails. All of those guys were super awesome and most of them added me on facebook XD.

Stone Temple Pilots in Lousiville, Ky. When Scott Weiland was still in the band. That man has an awesome stage presence.

Blue Man Group.
HANDS DOWN THE BEST CONCERT EVER.

ive never been to one

Living in the south in the USA, not many big name bands come around. And if they do, they usually don't come back due to low ticket sales. So I have only been to a couple of big concerts. My favorite one was in 2012, Memphis TN: Attack Attack, Escape The fate, with secrets,mest and the word alive. This World is Ours Tour! I had to travel for that one.

Eels, in Paris. I got to see E renew his "rock vows" with one of the older member in a kind of a wedding ceremony. It was really a show in every sense of the word.

same bro. I would love to see Kamelot though who I was planning on seeing and then they cancelled due to the previous lead singer leaving.

I saw Imagine Dragons last February, they were so great!

I went to a festival in The Netherlands a few weeks ago. There were lots of bands, but Royal Blood and Alt-j were really awesome
