Legal is an album by Brazilian singer-songwriter Gal Costa, released in 1970. The album returns to an accessible style following the experimental previous self-titled album Gal Costa of 1969. Legal is diversely influenced by psychedelic music, blues, and R&B.
The album cover is designed by Brazilian artist Hélio Oiticica.
"Legal" means "Nice" (or "cool") and it's an analogy to the singer's name, Gal.
