As you've likely already encountered 31384734987 posts on social media from your friends in bands, I won't go into further detail here on Bandcamp's one day ACLU support pledge, other than if you're reading this and it's still February 3rd--go buy some records, please!
I took this opportunity to purchase the entire Head2Wall discography (they're donating their proceeds to ACLU today too) and while I understand if you're not ready to take that plunge, you can test the waters by downloading their free winter sampler, which includes "Gary's Song" (from my not-yet-released record The Tuesday Night Music Club). It's a song about Mission Man, who coincidentally has a new best of collection available on bandcamp too. I'm not getting paid to say any of this.
Realistically, no one is reading this on any day of the year. But just in case, you can always donate to the ACLU at any time.
