Reading through this whole topic was weird... I think most people can't consider the other side of the argument. Or they're just not taking it seriously, which I sense in almost every post. It's just a joke to most people, this whole topic.
One thing I can relate to...
Saying that your favourite band is the best band in the world is a common thing. It's not arrogant or condescending unless it's meant to be, it's an emotional response to the strong connection you feel with that band. Try living your life taking everything at face value and see how far it gets you.
That's true, but I do have a habit of deciding who's my favorite band, and who I think the best band is. Which is funny, because both are opinion. My favorite band would have to be Porcupine Tree at the moment, and I think the best band is Tool. Why? Musicians who know how to communicate, know what they're talking about, can be thought provoking, are amazing on their instruments, and have a certain chemistry that no other band has. It's such a unity, and the music they produce is amazing. I don't think Tool is drawn out and boring. They are similar to Opeth in many ways, and different from Opeth in many ways. I suspect the only reason anyone could think Tool is drawn out, in comparison with Opeth, is the fact that Tool's songs actually flow and maintain structure while being able to pull off insane time signatures and differences. In comparison with Opeth, Tool is only boring because their early music consists of mainly passages that have nothing to do with eachother, and that's the TRUTH. Listen to
Black Rose Immortal. It's a great song, but it's Opeth's early stage. Tons of changes, but none of it flows. All of the passages are of the same LEAGUE, but they don't flow. Opeth, to this day, in my opinion, can't write songs like Tool does. Both bands are similar, but Opeth can't write songs like Tool. But that's just in comparison. I think that many of Opeth's songs are definitely considerable rivals, such as
The Moor,
Harvest,
Windowpane, etcetera, but they have a lot of other songs that just don't flow as much as most of what Tool writes.
I think that Opeth/Tool/Meshuggah would be an amazing tour. All of the bands are similar in some ways... The dynamics. At least Meshuggah's old stuff, which they should be asked to play some of. People will be used to hearing Meshuggah with Opeth, as they have already toured together, which will attract somewhat of a mixed crowd. The heaviness of Meshuggah, at least in comparison with Tool, with prepare the crowd for Opeth's degree of "heaviness." I just think it'd be an amazing experience. A theater setting would be best for it.
