After his return to Hollywood in 1983, Adler auditioned for Sunset Strip staple London.[10] When the audition proved unsuccessful, he formed the band Road Crew—named after the Motörhead song "(We Are) The Road Crew"—with his childhood friend Slash. They placed an advertisement in a newspaper looking for a bassist, and received a response from Duff McKagan. They auditioned a number of singers, including one-time Black Flag vocalist Ron Reyes, and worked on material that included the main riff of what would become the Guns N' Roses song "Rocket Queen." Slash disbanded the group the following year due to their inability to find an adequate lead vocalist, as well as Adler's laziness compared to himself and McKagan.[11] Adler then briefly joined a local band known as Hollywood Rose, which featured singer Axl Rose and guitarist Izzy Stradlin (who left shortly after).[12]
