Promote Your Music with Cassette Releases?

I just received the first promo cassette in a long time from Odessa Records' Shit Horse. Alright! Wait, what year is it? Fucking A. I have a cassette player in the basement, and I could go down there, grab it, plug it all in and give this a listen, or I could just send it off to be recycled care of Green Disc. Which one sounds like a better plan? Oh well. More music going unheard. At least I don't have to whine about watermarked CDs or the huge pile of stuff I dropped off at my pal's record store... PS: I won't even comment on the band's wonderful name. Look up my history of being in bands and you may see why!
