And i dont say this only because I like his music
“I’ve been venting about all this for years and [my manager] was like, ‘Write about it, Eric has the perfect joint.’ And, Lauryn Hill herself, she just had the raw emotion, the small things she said on the song was enough for me to push my pen and let myself be vulnerable.” Meth says his ability to let himself be so open is in line with the entire concept of the album, and its title.
“The national weed smoking day is 4/20, so I named my album 4/21 the day after. Because after that day, you have this moment of clarity when you’re not high and you see things clearly.” The Grammy-winner sighs and continues, a serious, determined look on his face. “You feel like you’re not in on the joke, and everyone’s laughing at you. I felt like no one was taking me seriously. I got real angry and I just starting writing.”
