Made a quick google search with "the best shoegaze albums", clicked on the first 5 results, Swirlies is there in 4 out of the 5 lists. They are even in Pitchfork's! If that means anything to you. But don't get me wrong, Swirlies is IMO better than those you always see leading those lists (MBV, Lush, Swervedriver, Slowdive, Ride), but they took a different path and stayed as a "true" independent band by not signing with any major label. There's another band I like better than Swirlies, they are very similar but with a marginally better production and more skilled musicians, they are called Luminous Orange and they rarely appear in those lists, but that's OK ;)
i've said it before but it bears repeating: "they spent their youthful days..." is a criminally under-appreciated masterpiece. It's on par with the most celebrated shoegaze/alternative /indie/whatever albums of its time. It blows my mind every time I listen to it.
One of the members from the Swirlies told me they have shitloads at Taang records that they're hoarding. I'm not sure if that's true or not. I emailed Taang and they said they had none, therefore the price for the LP is like 80 bucks. But yeah, one of the members said they're full of shit.
My dad works for Blonder Tongue Labs, the company that produced the Audio Baton. The LP is probably worth more than the company at this point. I've suggested they start printing "Blonder Tongue Audio Baton" t-shirts. I think they'd sell.
