Mental Notes is the 1975 debut album by New Zealand art rock band Split Enz. The album cover was painted by band member Phil Judd. Original vinyl copies featured Phil saying "Make a mental note" in the runout groove of the record's second side, causing the phrase to be looped ad infinitum until the needle was removed from it.
The album was a moderate success on its release in July 1975. It sold 12,000 copies in Australia, reached #35 on the album chart for one week, and peaked at #7 in New Zealand. Much of the material derived from Tim Finn's and Phil Judd's fascination with the work of the renowned English writer and artist Mervyn Peake – notably Spellbound, the epic track Stranger Than Fiction (their concert centrepiece) and Titus, named after the hero of Peake's Gormenghast trilogy.
