I'm sure some people here collect high-res album art scans for their music. I do, and I know how hard it can be to find them sometimes.
MegaSearch is a great site, and there are a few other sources online, but when it comes to obscure music, it can be almost impossible to find good quality scans.
I thought I'd set up a thread where people can request cover scans.
Here are some I'm looking for (at least 500x500, but bigger is better!). There are a few more, but I'll see if this thread takes off before I continue
Axiom Funk - Funkcronomicon
Blackalicious - Melodica
Hope Sandoval - Suzanne (EP)
Hope Sandoval - At the Doorway Again (EP)
Lyrics Born - Variety Show Season 2
