Sky Ferreira stopped by The Tonight Show last night to perform Night Time, My Time highlight “I Blame Myself.” The effortlessly cool performance (seriously, just look at those sunglasses) was accompanied by a brief web-only interview, in which she discussed how she wrote the song. She mentions she went mute for around 2 years, which she admits seems strange now.

Watch her perform “I Blame Myself” above, and check out her short interview below.
