Every story has a beginning.

G. Marq Roswell and TunesMap co-founder Nigel Grainge (in memoriam, 1947-2017)

The TunesMap story begins with a glowing, vintage, Wurlitzer jukebox.

It was the first thing film music supervisor G. Marq Roswell saw in the London home of A & R legend Nigel Grainge the evening the two first met and forged their lasting friendship. Grainge was an enthusiastic and fastidious record collector, and his jukebox was loaded with the greatest singles of all time. As they listened to hit after hit their conversation turned to what inspires songwriters and musicians, and what cultural influences give rise to songs that define an era. It was a discussion that continued over years, and when Grainge decided to digitize his extensive vinyl collection – including all original cover art – along with a corresponding video library, Roswell began to explore ideas on how they might bring to life the rich cultural context of the definitive music anthology Grainge had assembled. Both recognized that music streaming had changed the listening experience, and that context was all but lost in the digital music sphere.

Enter Erik Loyer, a Southern California digital media artist with a background in cultural technology and a love for music. Through many hours of conversation, multiple rounds of wireframes, mockups, and finally a series of working prototypes, Loyer elaborated the idea of cultural context into documentation, design, and code, demonstrating how it could be realized. Jon Blaufarb, a San Francisco music and tech attorney, provided the bridge to Silicon Valley, establishing key relationships with early supporters like Ty Roberts of Gracenote and providing important business expertise integral to any startup.

The four founders were joined by the team of talented and energized people shown below to realize TunesMap's grand vision.
