Sure, and of course double (or more!) albums were/are a thing. There was even a limited effort at players that could automatically drop a second album on top of a first when a side finished, then start playing the second record, and some pressings that put sides A and C on one record, and B and D on the other, so you could play two sides back-to-back automatically (by stacking the two albums on such a player). Though I don't think those were ever popular enough to much affect the art form.
Then there's e.g. classical music, where it wasn't unusual for one purchased unit of music to be a small box of several LPs. The album-as-an-artform, where "album" is usually one or two records created as a semi- or entirely-cohesive piece that was nonetheless broken into a bunch of shorter tracks and all crafted for the form and experience of the LP, was mostly a phenomenon for popular forms of music. IDK if "classical" music that was actually composed during the height of the LP was meaningfully and in some widespread way shaped by the LP record like pop music was, or not (I just don't know much about that music).
[EDIT] To be clear, what I'm talking about as far as the medium affecting the form the art took and how it was experienced isn't just things like full-on "concept albums", but attention to things like consistent tone or flow or placement of songs at the start of sides, or attention to which song ends a side and how that acts to draw one to the next side, or to close the current one, or whatever.
Most home stereos had a drop spindle, and most double albums has sides 1 and 4 on one platter and 2 and 3 on the other. Double albums were sure-as-heck an art form and not just a collection of singles. Between the 80 minutes of coherent music and the gatefold album cover art you could waste many an evening listening and looking at just what the artist(s) intended.
