Tanya Gallagher leads a double life. By day, the Pensacola, Florida native—who once interned for NASA—practices cartography, turning geographic information into maps for Santa Rosa County, where she resides. By night, she pens the kind of soulful, folk-inflected pop songs that comprise her new EP, One Hand On My Heart. Gallagher wrote all of the songs on One Hand On My Heart while she was pursuing a PhD in forestry in Vancouver. Heartbroken after a split with her longtime boyfriend, she nearly found the stress of academia too much to take. Instead, she found a healthy outlet in songwriting. Within a year, she had over 200 songs.
