Musician John Mayer teamed up with designer Jeremy Dean to create a commemorative t-shirt honoring the late Mac Miller. Announced during the "A Celebration of Life" concert, this special edition shirt is available for pre-order at $50. All proceeds are directed to the Circles Fund, which supports young artists, especially in underserved communities, continuing Miller’s dedication to creative development. The Greek Theatre event on Halloween night saw Mayer alongside artists like SZA, Travis Scott, and Vince Staples, celebrating Miller's legacy through music, with Mayer performing "Small Worlds," a track he originally contributed to.
