Samantha Hale says she is not a filmmaker. She admits to never having been to film school. And yet, her admissions form part of a voiceover at the beginning of her documentary titled 'Map The Music'. Part road trip, part soul search, it is an hour-long film that took Hale a little over four years to create in the wake of her father's death. Devastated by her loss, she believed it was a love of music that helped her heal, and set about trying to examine if others felt the same way.

The film (currently available at InSound.com) follows fans of musicians like Rachael Yamagata, Kate Havnevik, Zoe Keating and Jim Bianco. These aren't ordinary fans though; they are followers who, like Hale, walk in the shadows of their icons, trudging to as many live performances as they can in the hope of salvation. What Hale manages to tap into and draw, in the process, is an interesting parallel between music and faith: a belief system of sorts that helps keep millions sane.

At the centre of all this footage lies the force that is Imogen Heap ufffd the Essex-born, Grammy Award-winning singer-songwriter, Twitter-star and recent collaborator on acclaimed musical television series The Dewarists. It is to Heap's live performances that Hale, other fans, even other musicians, turn to time and again, citing the hold she has on her audience.
