"Scream Aim Fire" is a really good album and awesome second release from Bullet For My Valentine. A friend of mine got me into them last year, but it wasn't until I heard this album a while ago that I really got into their stuff. And I'm glad I did, because there's actually a lot of great stuff on this album.
BFMV may get lumped into the ever-growing subgenre of metalcore bands, or emo, or whatever the stereotype is, but actually I hear a lot of influence from bands such as Iron Maiden, Metallica, Trivium (well, they did have a metalcore sound early on, but they're still awesome!), even a little Megadeth and Slayer. There's plenty of great riffs, solos, lyrics and drums throughout this album, and the standout tracks to me are:
"Scream Aim Fire": The title track is the opening song off this album, and it comes charging at you at 100 miles an hour! Lots of great, heavy riffs and a mind-blowing growl that Matt Tuck holds for a long time!
"Eye of the Storm": Another high-energy, fast-packed song with more awesome riffs and soloing, with cool lyrics to boot.
"Hearts Burst Into Fire": Reminds me a little of Ozzy's "Mama I'm Coming Home", but faster and more rock-y. A beautiful, clean guitar opens with a passionate solo over, then some melodic, fast riffs and nice vocal melodies bring us through the rest of the song.
"Waking The Demon": An aggressive song with heavier riffs and darker lyrics, but actually feature some nice vocal melodies, a cool drum fill and a wild guitar solo. Plus, the vocal-only ending of "Wa-king the deee-mon!" is epic!
"Last to Know": The shortest song on the album, but still packs lots of energy and darker lyrics in the vein of "Waking The Demon" while still maintaining the quality musicianship of the band.
"Forever and Always": Another melodic, ballad-styled song that ends the album in a great way. A bunch of cool riffs fill this six-and-a-half minute plus song up and leaves you feeling great.

Although I feel the rest of the album could use a little more variety in the feel, such as the progressive, ballad style of songs such as "Forever and Always" or "Hearts Burst Into Fire" to make the album more dynamic and interesting, "Scream Aim Fire" is still an awesome metal album that you should check out today!
If you wanna hear a mix of speed, melody, talent, heaviness and even lightness wrapped together, get your hands on a copy of this! I'm eagerly awaiting BFMV's next album, thanks especially to this one! Thanks for the time, and peace.
