That continued with the release of Felt 2: A Tribute to Lisa Bonet, in 2005, by which time Murs & Slug's creative partnership had been elevated to a cult-like status, and intensified further in 2009, with the release of Felt 3: A Tribute to Rosie Perez.
While their personal relationship is fundamental to Felt's legacy, with their comradery establishing itself as a driving force for their creativity, the production on Felt albums has also been a major part of their success. The beats on the first release were provided by another member of Murs' Living Legends crew, The Grouch, while the second album was produced by Ant of Atmosphere, and the third by Aesop Rock. With notable changes in the sonic backdrops for each album, the MC's were allowed to share a unique side of themselves each release, while fine-tuning their styles and showcasing their own growth. The decision to use different producers for those albums was an integral part of the group's journey. A lot has changed since their last release in 2009, including for Murs and Slug themselves in both their personal and professional lives. Their careers have continued to elevate and their families have continued to grow, and this fourth album is something of a reflection of those changes, starting with the title of the project itself. Felt 4 U seemed the simplest, most direct way of saluting the fanbase that has made Felt what they are, a thank you to the dedicated; as well as moving away from the perhaps more male gaze-feel of the previous titles. Even amidst the changes we still find familiarities, like Ant making a return to handle full production on Felt 4 U. Sonically, the album is overflowing with the influences of funk, soul, blues and even country flavors. While Felt 3 had a wintery feel, Felt 2 sounded perfect in autumn and the first Felt captured the blossoming sounds of spring, this is a distinctly summery album, with the richness of Ant's production creating an overall warmth that envelops the whole project. From the opening chords of "Never's Enough", with it's funk-fueled, vaguely retro feel, to the outrageously smooth vibes of "Underwater", this is a rap album that demands as much attention for the music, as it does for the rappers themselves. The album is unique to the Felt catalog for it's inclusion of guest artists though, with four features making their way onto the final cut. The aforementioned "Underwater" features an excellent appearance from Blimes, who brings her inimitable style to the hook, and Blueprint is credited as his alter-ego, Shepard Albertson, thanks to his vocal support on "Crimson Skies", while The Grouch and Aesop Rock join in on "Hologram" making the perfect Easter egg for Felt fans, thanks to their contributions on previous projects. Overall, this album provides the perfect segue into Felt's next chapter. It reflects changing attitudes in the culture and in the world as a whole, and it reflects the changes in Murs and Slug as well. Whereas before, when some songs were delivered with perhaps a slight tone of judgement - for want of a better word - on Felt 4 U we find two artists offering us their opinions and viewpoints in the hopes of furthering discussion. It's exactly what's needed in the current climate and also a sign that the Felt story is far from over.
