Surely you must be confusing Epica with Within Temptation there, mate. Sorry, but I just find it hilarious that someone who's able to write full paragraphs on single songs... no, single parts of songs when it's Opeth or Symph X is able do say this based on some really skin-deep similarities.
I don't mind first- and second-ratedness that much (although I personally find Epica to be lights ahead in musical proficiency and to be much less trivial in their composing (though not as catchy), which makes me wonder about this "second-ratedness" in general) but they are not even that similar.
This one annoys me just as much as you guys were annoyed by me comparing Symph X and Dream Theater - some general similarities do not make the bands alike. Draconian also have a female singer, but even if they used orchestra, that would not make them a Nightwish clone. Maiden might have even been inspired by Thin Lizzy and use the sweet guitar harmonies, but the bands are not much alike.
I'm not even a huge fan, it just annoys me, because there are many other bands that are actually annoyingly similar to Nightwish, but this here... like I said:
"Dude, Symph X are just a second-rate Dream Theater, and they've ever done anything to convince me otherwise. 'Cause, like, both bands have virtuoso guitarists, keyboardists and drummers, play long songs, are metal, have used polyrhythms and both reference some form of classical art in their name, but DT are, like, older, have better chops, catchier choruses and feel more professional in their self-presentation".
I'll admit that I have not listened to much Epica, but what I
have heard reminds me of Nightwish. I'm sure they have a ton of material that doesn't sound like them, but when you have a female opera singer, heavily orchestral arrangements, and aggressive male vocals, the comparisons are going to be made. The two bands share a
lot in common.
Calling Epica a second-rate Nightwish is just my opinion. I prefer Nightwish's vocals (all three of them, honestly) to Simone, I prefer the songwriting style, and I prefer Marco's vocals to the guy in Epica's screaming. I can't stress enough how much I dislike that screaming, and how much it lowers the quality of Epica for me. So in summary: I have not heard much of Epica's discography, but
from what I have heard, they are a band with many similarities to Nightwish. From this song alone, Epica's musicians are definitely stronger - but Nightwish's talent was always in the songwriting and vocals for me.
If you've heard only a few Symphony X songs, depending on the songs you heard, it's certainly possible that you could find many similarities to Dream Theater. They are both bands that play heavy music, they both have singers who can wail, they are both beyond technically proficient, they both often write long songs, and they both have prominent keyboards. But if you break it down, they are truly not similar in their style and songwriting approach. Dream Theater has a nasally singer, they often write pieces that are designed
specifically to show off, and have a far more diverse songwriting style. John Petrucci plays acoustic/clean pieces often and incorporates folky chord strumming into the songs, whereas Michael Romeo almost always arpeggiates clean chords. This leads to a radically different sound, with Dream Theater's being far more traditionally commercial. They've experimented with every genre I can think of, minus country. I truly struggle to even call them a metal band, because that's not even half of their sound. They're a progressive rock band who have been influenced by everyone under the sun. They are also more lyrically mature, usually penning songs about life experiences and broad, big-picture philosophies. They are without a doubt more professional in their approach, but there are a myriad of reasons for that and I'm not going to get into that right now.
Symphony X is a progressive metal band. It's truly difficult to describe them as something else, because that's simply what they are. They have metal songs and they have progressive songs, with many being somewhere in between. The guitars might get wanky in the solos, and there might be crazy fills (on all instruments) here and there for a little extra flavor, but outside of that, they're not writing pieces to show off. Their technical ability is usually woven into the riffs and spread out more evenly throughout a song, rather than saved for a big mandatory 5-minute out-of-place instrumental section. The songwriting flows well and their transitions are typically excellent. Russell Allen is gritty, aggressive, and bluesy - the polar opposite of James LaBrie. They are more riff-based than Dream Theater and typically forego big sweeping half-time bridges and choruses in favor of keeping the groove of a song intact. Their influences are not as diverse as Dream Theater's - mainly classical, orchestral scores, '80s metal, and classic prog rock. They've dabbled in jazz, but not often. Lyrically, they used to stick mostly to mythology and classic works of art, but have lately watered down their sound with vague "tuf guy" metal lyrics. Regardless, that's again a polar opposite of Dream Theater. Performance-wise, unlike Dream Theater's epic productions, they are very "meat-n'-potatoes." They're just, y'know, dudes who show up to a gig to play complex progressive epic metal. Their overall vibe is
completely different.
I'm sure if I listened to Epica's entire discography, I'd find plenty of things that set them apart from Nightwish. In this song, I'm a fan of the choral/orchestral arrangements in some parts, and I do like the piano. They're definitely far less self-indulgent than Nightwish with Tuomas and his spoken-word fluff. The "riff" at 7:10 is great. But it is
really difficult to not hear Nightwish whenever Simone is singing (especially during the big choruses). For the record, I do not
dislike Epica - they just often struggle to fully immerse me into their works. This is far and away the best track I have heard by them, and perhaps I've only heard their shorter, "poppier" works in the past. Do they have any albums (or songs) without the harsh vocals? It sounds like they're in the same style as Opeth's (gutteral), but I
love Akerfeldt's growls and greatly dislike these.
