Episode 51 kicks off with an acoustic version from a band with a long long long name and closes out with a 'previously unreleased, momentarily released, once again unreleased' Shakey Graves tune. In between those you'll hear Sufjan, Two Gallants, Hiss Golden Messenger, and a whole bunch more, so I'll just stop listing so you can just get listening.
The Mix Tape Radio Show is a series of mix tapes put together by HI54LOFI. He's been doing it for years; sometimes with new episodes every 2 weeks, sometimes nothing for months. He's sketch like that. But the tapes are pretty solid pieces of ear candy & there is a large accumulation of them to bridge any time gaps—so all is forgiven at the end of the day.
