I often like the overlooked gems more than the "important" records. I'd pick White Album over Sgt. Peppers any day, for example.
In the overwhelming majority of cases, I've gotten into an album long before I was aware of it's critical or fan status. I remember being quite pleased when I read that Deep Purples' "Fireball" was regarded as part of their trio of classics because I already thought it was a great album. The same article mentioned "In rock" and "Machine head" as the other two. In rock turned out to be that, Machine head did not. But I love their debut, "Shades of Deep Purple" and their original last album "Come taste the band" and one rarely hears anything about them.
It was 25 years before I began reading of "Physical grafitti"'s status. But I'd been in love with it that long. Whereas their debut was held in almost mythic esteem but I was never impressed by it. It took me years to appreciate it. With the Beatles, I so fell in love with their music that pretty much anything of theirs I liked. When I heard Pepper, I thought, as I still do, that it was a fantastic album. It was after that that I heard about it's mythic status. But I loved "Revolver" and "Rubber soul" 20 years before it was fashionable to hold them in high esteem. I dug "the White album" and "Yellow submarine". I recorded them illegally at my school. I just thought they were great.
I think I'm like that with most bands actually. A good report can't make me love an album.
How heavy can you be while still remaining both melodic and memorable?
I think that in heavy rock's initial flourish {I count that as '66~'80}, as heavy as the bands were, most of the groups wrote
songs and used heavy and hard rock {hard rock is just heavy metal with the amps set to 8 !} to present these songs, as opposed to some groups like maybe early Grand Funk Railroad that had a heavy rock style and used songs to present this. There's quite a difference in my mind. I mean, I love the Funk, but there is some justification for the NME's categorization of their stuff on their first few albums as "song after song of tuneless heavy metal". I love "Live album" but it is kind of that way. Whereas Led Zeppelin, Deep Purple, Black Sabbath, Budgie, Nazareth, Cream, Status Quo, Aerosmith, Blue Öyster cult, Cheap Trick, AC/DC, Kansas, Hendrix, Kiss, Lone Star, Judas Priest, Thin Lizzy, Motorhead, Triumph, Mahogany Rush, Boston, Rush, Wishbone Ash and a host of other heavy bands wrote catchy, melodic stuff with hooks galore {yeah, Quo and Motorhead were pretty hooky !}.
I've long felt that also, their vocalists knew how to sing because
they had to. They came up in or were inspired by the era where the vocal {and by extension, the vocalist} carried the song so the melody had to be memorable. The real skill was in how this was all fused together, the power and the melody.
I can't get into NWOBHM I'm afriad - the style, tempo & songs just aren't mine to embrace.
NWOBHM was a bit of a disappointment to me. I first heard of it in 1980 and because it fell plumb in the midst of my heavy rock odessy, I expected big things so it was probably my fault.

I remember my Uncle's girlfriend was coming out on holiday to Nigeria where I was living at the time and I asked her if she could bring me two LPs, "Argus" by Wishbone Ash and this one, "Metal for muthas" which featured some of these NWOBHM groups {and an older band, Nutz}. I especially wanted to hear Toad the wet sprocket and Ethel the frog. Well, she got me "Argus" but not Muthas........When I got back to England the next year, I wasn't keen on any of the new bands except Leppard's debut. Still one of my faves. Most of my heavy records came from that '79~'81 period. Interestingly, I added very very few heavy rock records after 1981 to my collection.
Twee Brit Psych annoys me - those gnomic tomes on Piper drove me away from the album for a while. I like lots of Brit Psych but skip the twee stuff - AND that goes for much of Sgt Peppers: The music hall lifts didn't do it for me.
I have to say, I'm a sucker for the twee {that would make a great album title !}, whether it be British psychedelia or American 70s pop or jazz or folk or anything. I like a bit of whimsy, though no one does it like the English.
Slade is brilliant. You should really check out bands like Saxon or Horsepower, they have very sweet/slade-influenced hard rock.
also, i love Budgie. Cruelly underrated band.
I like quite a bit of Budgie's early to mid 70s stuff. I was something of a late convert to them. Had I gotten into them when I was on my heavy rock kick circa '79~'81, I probably would've appreciated them more. That said, "In for the kill" and "Napoleon Bonapart" would definitly be with me on my desert island ipod.
I loved Slade and the Sweet as a kid, indeed, the first single I ever owned was "Blockbuster". From '73~'75, they knocked out some of the defining songs of my chilhood. "*** on feel the noize" sparked off a frenzy of kiss chase at my school that dethroned football for a month during our playtimes. Reality soon asserted itself though ! The "Girls, grab the boys" line was taken as a command by the girls in my class. Kids
believed in pop music in those days ! There was a guy in my class called Kieran McCrystal and even though I've not set eyes on him since 1974 and we were never exactly friends, whenever I hear "Hellraiser" and "Ballroom blitz" I think of him. I wish they didn't, but they just always remind me of him.
When I got a little older I listened with both ears to both bands and found them to be far more than was ever apparent at the time. I still listen to their stuff now. Skillful.
