Normally, we would be gearing up to see some of the best a cappella groups in the area perform in a two day extravaganza. This year will be a little different, but as the saying goes -


The Show Must Go On!

Every day during the month of April, we will be featuring virtual performances from the groups you have come to know and love over the years as well as some groups that are new to our a cappella community.

Performances will be released every day. Don't miss a beat and make sure you are following us on your favorite social media platforms.

April 6th


One of the great things about ACA-Pocalypse is the opportunity to highlight newer a cappella groups in our community and #acapocalypse 2021 is no different. This is Hannah Fuller’s (CHS 21) first arrangement, but you wouldn’t know it from listening to it. After throwing herself into the arrangement the drumline came to her first as it was one of the things that drew her to the song. Hannah shared that “Simply being involved in the music department and going to a fair amount of a cappella workshops and performances, I picked up a lot of stuff, but this was the first time I’d actually taken that knowledge and applied it. Thank you for taking the time to listen to my stuff. Creating it was really fun. Hope you enjoy!”

Thank you Hannah for sharing this with us … we definitely enjoyed it and look forward to everyone enjoying your performance of “Believer.”

April 7th

April 10th

For their #acapocalypse2021 arrangement of “Stay With Me,”

The Thursdays members Danny Sousa and Josh Timmins were inspired by the works of Street Corner Symphony and Kevin Olusola.

Josh had this to say about their creative process: "Our arrangement is very eclectic because we made it up as we went along. We didn’t write any of it down; we just went for it. We wanted a more traditional music video style rather than faces in boxes (since there are only two of us) and wanted an outdoorsy urban-ish vibe, so we went to the mills in Vinal Square."

Enjoy !!

April 9th

Established in 2003, The Jewel Tones is the only co-ed, faculty-directed a cappella group at Marblehead HS.

The Crescendos member Eleanor Desmarais (CHS '23) created this video as a birthday gift for her older sister Evelyn, who is also an alumna and founding member of The Crescendos.

Eleanor says: “I have always been great at harmonizing parts together, even though I can’t read music. “ She credits her mom with helping her to assemble the video.

For #acapocalypse2021 this evening,, we invite you to enjoy Eleanor's performance of "When It's Time."

For tonight's featured #acapocalypse21 performance, please enjoy "Somewhere Only We Know" by Trills 'n Chills !!

April 23rd


Tonight's featured performer is Nhyira Nkansah. Nhyira is a member of

The Crescendos

. In her own words "What inspired me was the fact that I have listened to this song on repeat for years, and I really thought I could take it and make it my own. I had no prior experience so it was very off the dome and experimental. To come up with musical elements I listened to the song non-stop trying to dissect all the individual sounds that were used vocally and instrumentally. For the video, I didn’t want to do too much so I made a mini animation of my head with music notes, to represent how this song is something that I am always singing in my head and my take on it represents how I hear the voices in my head sing it. This project is something I’m proud of because it was a challenge, but I pushed through. I’m glad I went through with it!” We invite you to enjoy Nhyira's performance of "On & On"

April 24th



is North Reading HS's coed a cappella group. They travel throughout New England and the United States performing for communities, festivals, and competitions. You know who they are when you see the "green" hit the stage.

For those who have been following our virtual #acapocalypse2021 posts all month, you know Sundays are reserved for featured & headlining groups from our previous shows. Tonight we celebrate

Pitch, Please

from Northeastern who was scheduled to be our headliner around this time last year. Fate had a different plan but we still love this group and would love to work with them again in the future (... got any plans Spring 2022?).

When we planned to highlight them today, we had no idea that it would be the same day they were going to release this incredible performance of "Babybird" from ICCA 2021. Enjoy!!

April 26th


CHS juniors Sachi, Lily, and Jackie have been singing this song together since 7th grade! Jackie remarked that ‘we all love La La Land, and City of Stars has a hopeful and dreamy feeling to it. For a trio, it is a great piece to experiment with harmonies and the lyrics “That now, our dreams many finally come true” echo what all of us feel when we sing!”

Sachi has had prior arranging experience writing for The Crescendos along with her class mate Zoe. Their joint arrangement of “Still Haven’t Found What I’m Looking For” was part of the group’s 2021 ICHSA set. Jackie has dabbled in arranging, but this was Lily’s first venture.

Jackie had this to say about their creative process: ""Sachi included reverb when mastering the audio for this because it adds an eery, dreamy effect to the arrangement. We all wanted this to be a simple trio with the background voices echoing-as if the stars in the city were beckoning us to find them! We chose an echoing effect to blend feelings of hope, nostalgia, and dreams. Lily put together the video and we chose a color scheme that was similar to the color palette for La La Land: warm and golden twinkling lights to represent stars, deep blue to reflect the uncertainty of the sky/future, and a faded purple to represent a dreamy illusion. The audience should know that this arrangement is not supposed to be extremely involved and complex. It’s simplicity represents the reflective and curious feeling of the song: “City of Stars, are you shining just for me?”

For tonight's #acapocalypse2021 featured performance we invite you to enjoy "City of Stars" from these members of The Crescendos and The Thursdays.

April 27th

As we approach the end of April and with it the end of our Virtual #acapocalypse2021 we at the ACA wanted to take a minute to say "Thank-you" to everyone that is a part of our a cappella community. It has been an honor to be able to share your creativity and musical talents throughout the month. We have three more performances to come as we close out the month, but tonight we wanted to share with you a highlight from ACA-Pocalypse 2019 when Chelmsford's Crescendos and Marblehead's Luminescence took the stage together to perform "The Parting Glass" - a musical representation of this "Community."
