April is known for rain, taxes, rabbits, and silly pranks, but now the month has a new, much cooler holiday: Boston’s mayor, Marty Walsh, has designated April 9th “Riot Grrrl Day” in honor of Kathleen Hanna, the front woman of Bikini Kill and Le Tigre. Born in Portland, Hanna's interest in feminism came at an early age. After dabbling in spoken word performance, she realized that her message would be louder if it was delivered in music.

How can you celebrate "Riot Grrrl Day"? Start by listening to this playlist of badass female-fronted acts.

1. Sleater-Kinney "Bury Our Friends"

After a long hiatus, Carrie Brownstein, Janet Weiss, and Corin Tucker reunited Sleater-Kinney with the album Bury Our Friends. Check out the title track above: “Exhume our idols and bury our friends/ We’re wild and weary but we won't give in.”

2. Speedy Ortiz "Raising The Skate"

Speedy Ortiz is fronted by vocalist/guitarist Sadie Dupuis, who created the witty, anxious "snack rock" that rocked SXSW this year. 3. Screaming Females "Hopeless"

New Jersey's Screaming Females is actually just one female. She may not exactly scream, but guitarist/singer Marissa Paternoster has earned the description by belting rock vocals that defy her size. 4. Bikini Kill "Rebel Girl" Of course, we couldn't make this playlist without including the person who inspired the holiday: Kathleen Hanna, the original rebel girl. 5. Le Tigre "TKO"

Hanna's next project, Le Tigre, is more polished, but just as fierce:“I’ll say my piece and when it’s over you’ll be on your knees," she sings, while rocking a suit in the video for "TKO."

6. White Lung "Down It Goes"

These Canadian punks are led by singer Mish Way, who is also known for writing edgy articles and putting douchey audience members in their place. 7. Perfect Pussy "Work"

Meredith Graves is the woman behind the heavy-hitting, possibly-unsafe-to-google punk band, Perfect Pussy. 8. Waxahatchee "Under A Rock"

Waxahatchee is named after a creek in Katie Crutchfield's hometown in Birmingham, Alabama. Now living in Brooklyn, the singer-songwriter just released her third album, Ivy Trip. 9. Tacocat "You Never Came Back"

Tacocat is here to prove that cat ladies can be cool, too. The Washington State surf-pop group plays upbeat songs that address feminism, as well as topics related to cats and everyday life. 10. She Keeps Bees "Saturn Return"

The husband and wife duo has a name that almost seems like a warning- as in, "watch out for that chick; she keeps bees." Their sound is a slow, bluesy creep that builds and sneaks up on you.
