I catch up with singer-songwriter Emm Gryner. The Canadian artist recently released "Only of Earth,\u201d the first in a planned trilogy she calls Days of Games. She toured in the late David Bowie\u2019s band and more recently helped her friend, the retired astronaut Chris Hadfield, record a version of Bowie\u2019s Space Oddity, which was recorded partly onboard The International Space Station. Emm also talks about the cover songs she has recorded.
