Think Again, before Digital Recording era started, During The Analog Recording era, The First Vinyl Pressings Are Essentially like Witnessing a Musical History Being Made ; that too a first hand witness...Classic is a polite term for obsolete then?
Still valued for their aesthetics and nostalgia and no availability though
So in Recording Studios of 70s, be it Lyla by Eric Clapton or Led Zeppelin recording Stairway to heaven or Miles Davis Recording Birches Brew, The First Vinyl Pressings Are Essentially First Hand Witnesses of Musical Milestones of History, in the Making! That's a remarkable thing IMHO, Especially considering the fact that Subsequent Analog Pressings do degrade the sound by a very minute bit. Next better options are the best sounding First Pressings and Best Remastered First Pressings.
Absolutely, if those First or Best Sounding Recordings are well preserved & still available for buying now (that's well preserved for almost 50yrs), will definitely have a snob value, vintage appeal and horribly skewed Demand Supply Equation leading to unbelievable valuations. Other than those well preserved recordings rest everything is akin to Scam and money minting from a New Trend that's all.
The Whole Analog Music Reproduction may appear cumbersome from current digital era perspective (But Analog playback should be compared with how cumbersome it would have been to arrange a live music band playing, because that was the only other option available before Analog was available) , but if you are chasing a great sounding recording especially the ones recorded before 70s, Analog chain surpasses the digital by a decent margin.
But the current trend of digital masters being used for Vinyl, pressings to fill the demand supply gap, doesn't make sense to me per se.
So, its all worth if you have good unique recordings and time /patience, otherwise its just an exercise in futility when much better options are available.
