God, between this and getting Sabbath a couple days back, I'm getting a lot of albums that I have some history with. I was kind of raised in metal, so to me this is an absolute classic (but not quite my favorite Maiden, that's probably Powerslave). To me, this is kind of archetypal "Heavy Metal" so much so that I almost can't put the sound of this into words, its just metal to me, but I'll try. Basically the New Wave of British Heavy Metal (NWOBHM )is *one of* the earliest genres of metal that very specifically held itself separate from hard rock in a post Sabbath world (note that while Sabbath was *very* important to this movement, this sounds totally different from Sabbath, whose best music often slots a little neater into Doom Metal which would get more established later). Iron Maiden formed in 1975, when the genre was still kind of being hammered down, but their first album got released in 1980, when everything was a little more established. Maiden's sound kind of lands between more melodic metal at the time, and what was thought of more as speed metal. Maiden operates at an energetic gallop, but they never give up a catchy chorus as a consequence of it. Some of the things that distinguished Iron Maiden from their peers was *a little* prog influence, which mostly showed in their song structures, riff writing, and later, high concepts. Additionally, Maiden had two lead guitarists at this time, which allowed them to play with guitar harmonies. As a consequence, the solos on this are *awesome* with Dave Murray and Adrian Smith playing the aforementioned harmonies at some times, and trading dueling passages at others, the effect is electric. Honestly, the whole band is super tight, Steve Harris' bass work is mixed high, and is very distinct and enjoyable, and Clive Burr may not be Maiden's most iconic drummer, but he holds down the fort on this album. I also have to mention Bruce Dickinson, he's a super charismatic frontman with a very distinct and powerful voice. The songs on here are consistently energetic and exciting, and while the A Side here is great in its own right, the B Side here has some classics, The Number of The Beast, Run to the Hills, and Hallowed Be Thy Name are all iconic Maiden songs. Some lines on Run to the Hills have aged a *little* awkwardly, but overall *I* think it has aged a lot better than I think something like this could have, especially because, at the end of the day, it's Maiden's earnest attempt at making a song calling out British Colonialism. Anyways, the song is driven by an iconic galloping lead riff, catchy melodies, and a soaring chorus. Number of the Beast is a wonderful blast of hokey Satanism, conjuring grim rituals and tall shadows, and also it just absolutely rips. And Hallowed Be Thy Name is Maiden's grandest statement here in its lengthy, multi-phased structure and lyrics about a death row inmate in grim denial. It is filled with incredible passages, and epic riffs and is one of Maiden's greatest songs ever. The rest of the tracks here may not consistently reach these highs, but they are pretty great songs in their own right. I will say I've seen people complaining about the lyrics here, but they are good enough to yell along with at a show, and I think that might be what really matters here. Overall this is just cool, Maiden has an iconic metal sound, and they consistently deliver great songs, its a blast.
