Resources like The 365 Days Project, where one outsider MP3 per day was posted in 2003, the song-poem documentary Off The Charts, writer and broadcaster Irwin Chusid’s Songs In The Key Of Z books and CD compilations, and the web site of his radio home, WFMU in East Orange, New Jersey, will open musical windows you never knew were there.
Also never erase any cassette from a thrift shop or yard sale without spot-checking it first. You never know what instant outsider classics might be on it, like there are on those old tapes of you singing along with your mom’s Abba records.
