Gustaf Grefberg is a Swedish musician and video game composer. Within the demoscene, he is known under the artist name Lizardking, and much of his production consists of tracker music. He is or has been a member of the demo groups Alcatraz, The Silents, Razor 1911, The Black Lotus and Triton. Grefberg became one of the most widely recognized Scandinavian tracker musicians during the 1990s, known for his melodic style and polished production techniques. Together with Joakim Falk, he invented a musical style called Doskpop, characterized by upbeat melodies, pop‑influenced harmonies and Amiga‑style sound design. He released several music disks such as Doskpop The Compilation and Memorial Songs 1+2, which helped popularize the style across the demoscene. He also contributed to projects such as Merregnon and the Symphonic Game Music Concert series in Leipzig, Germany, where his work was performed alongside other European game composers. In 1994, he released a compact cassette, Mindlitter, in cooperation with Martin Wall. Grefberg's songs appear on side A and Wall's on side B. The two sold the tapes in person at the Assembly '94 demo party.
