Pink Floyd : Darkside of the moon.
Beatles : White album
Dire Straits : Dire Straits
Cream : Fresh Cream
jimi Hendrix : Electric Ladyland
Jethro Tull : Aqualung
Iron Butterfly : In-a-gadda-da-vida
Some more?
I have to think about! 
Good List. Some others that come to mind:
Nirvana - Nevermind
Guns 'N Roses - Appetite for Destruction
Metallica - Master of Puppets
Iāll add
The Beatles Abbey Road
The Who Quadrophenia
The Rolling Stones Let it Bleed
Led Zeppelin IV
100% Dark Side of the Moon
Now you guys are going to make me think perhaps after work I may have an album or two to add
Do that please!
Seems that there is NO album published > 1990.
I donāt know nothing about the music scene -> 1990.
Is there really no album to mention?
Make sure not to forget The Stranger by Billy Joel from 1977
okay here are a few that changed rock
Never mind the bollocks heres the sex pistols- introduction of punk rock in mainstream music scenes and clubs
hatful of hallow -the smiths movement toward britpop
Suzi Quatro- suzi quatro - āno other prominent female musician worked in rock simultaneously as a singer, instrumentalist, songwriter, and bandleaderā. According to Auslander
Dashboard Confessional - The Swiss Army Romance
This was released in 2000; much like Nirvana brought Grunge into the mainstream, this album brought āemoā (and multiple evolutions) into mainstream. There were much bigger bands that came after (My Chemical Romance for instance), it was was a full-on āemoā that was an alternative to the post-grunge/nu-metal/pop-punk era (Finch - What it is to Burn is often considered to be THE transition album).
Anyway, rock music >2010 Iām too old for so good luck 
Dark Side of the Moon. Testing new speakers and headphones for nearly 60 yearsā¦ .
So you must be over 80 now.
What kind of speakers did you test 60 years ago?
I can tell you some brands I came in touch with 50 years ago.
Unfortunately no bluetooth!
