Mauri Martin (aka No Shape & Tremmme) released his debut album in 2010, blending Bilbao’s hip-hop scene with electronic music. From 2010 to 2013, he was a resident DJ at Fever Club, supporting acts like Steve Aoki, Dirtyphonics, and Pendulum.

In 2014, he moved to Madrid to work as a songwriter for Sony ATV Music Publishing, contributing to major Spanish artists and projects, including Spain’s 2016 Eurovision entry. That year, he also launched No Shape, a project fusing soundtrack elements with house and electro.

Between 2016 and 2020, he collaborated extensively with soprano Miren De Miguel under the project "Allegro ma non troppo" , experimenting with opera arias, electronic tempos, and live video mapping. In 2019, they performed on Got Talent Spain, earning a standing ovation from both the audience and jurors.

As a longtime ghost producer, much of his work remains behind the scenes, making his eclectic catalogue hard to trace online.
