Grand Funk Railroad – Survival

In recent years I've become somewhat tired of the old blues-based hard rock of late 60s and 70s bands. It's a sound that I loved years ago, but after hearing so much of it, along with hearing many other styles of music, it begins to sound uninventive and stale. Not to mention that blues rock is frequently just a rehashing of what more original artists made years before.
Grand Funk was not a band that I ever listened to during the musical "development" of my teen years, allowing a fresh introduction to them now in my 20's. It's been a while now since those first listens, but even from the beginning I can remember just how fresh and unique this sound is. "Survival" was my beginning with the band, as I found a decent copy in a junk stack of about 300 records I payed $15 for. Anyways, back to the music. One of the first things I noticed when listening to "Survival" was how incredibly tight this trio is. This immaculate unity makes each track's grooves immediately obvious and intoxicating to the listener.
One of the most obvious elements to the Grand Funk sound is the HEAVY humming drone of the bass guitar. It's an undeniably badass sound. In my estimation, this is where the genius of Grand Funk's songwriting and performance comes in. By frequently using the massively deep and heavy bass guitar as the lead instrumental, establishing the melody, it allows a ton of space in the high end of the mix for the vocals, guitar, keys, and most importantly the drums. The use of the drum kit is what I specifically find so genius about this band. It is about as tight of a snare sound as you'll hear on old rock albums, almost more in line with some jazz or marching band drumming. With the bass occupying so much of the low end, and guitar and keys only taking up minimal space in most instances, the kit and specifically the snare is super prominent in the mix. To increase the kit's prominence even more the drums are basically hard-panned to the left channel, while the bass takes up most of the right. Honestly, I don't know how to explain what makes the drum sound so great, or "genius", as I have now said multiple times, as it's something that the listener truly needs to hear for themself. Maybe it's the contrast of having such a heavy chugging bass with that snappy, tight snare that is so captivating. I could also see why people would dislike this, as the separation of drum and bass is so distinct.

i´m from Chile and i have one, but without the photos :/

I have a copy of this LP with a completely white label in a completely white sleeve. There are absolutely no words or anything on the label. On the sleeve it says 'Stereo LP Record'. There is a matrix/runout number of A8-1 and A8-2 on the vinyl. Anyone have any idea about it? Is it a bootleg? A demo? A pre-release? Please let me know as soon as possible! Thanks!
