GRX is a moniker used by Dutch electro house DJ and producer Martin Garrix, primarily for releases that fall outside the typical sound and style his main stage name is known for. Under the GRX alias, Garrix explores various electronic music subgenres with a distinctive edge, allowing him to experiment with different sounds and collaborate with diverse artists. His most prominent work under this persona includes the singles "Boomerang," in collaboration with Brooks, and "X's," featuring Icona Pop, which received further attention through remixes by Seth Hills and Osrin. Despite the different name, GRX's productions maintain the energetic and polished quality that has become synonymous with Martin Garrix's brand.

With a less frequent release schedule than his primary project, each GRX track garners significant anticipation and excitement from fans of Garrix's work. "No More," "Far Away," and "Restart Your Heart" continue to showcase GRX's ability to create captivating electronic compositions that resonate with a wide audience. Despite the alias, Martin Garrix's creativity and mastery in electronic music production shine through GRX, allowing him to connect with his audience in new and unexpected ways. Whether on a festival stage or through streaming platforms, GRX continues to contribute to the vast and dynamic landscape of electronic music.
