In 90s three mysterious tracks with the name "Earth Jam 1968" found in the traders circle.Also they released on "Accidental Overdose" bootleg which includes the sbury Park Convention Hall 1975 live.Also exist a two minutes sample from these on You Tube.But this one is the full stuff,almost 45 minutes,of this strange bootleg.Most of
Black Sabbath fans said that is fake.Also exist a Iommi's interview who told that are fake and nobody Black Sabbath's member play on these.Who is this band?Nobody knows.Maybe was a band with the name Earth,but no pre Black Sabbath band.Anyway listen this jams,are interesting and have some very good moments!Also these tracks are from my "Accidental Overdose" personal copy.I hope to enjoy it!!!
