Riley has been singing since birth, and now at 15, has fronted Modern Yesterday for over 4 years.  A true 90s kid born two decades too late, Riley is a huge fan of female fronted rock/metal bands. Her favorites are Paramore, Evanescence and the Foo Fighters (Dave's not a female but he is THE BEST), and her favorite vocal queens are Hayley Williams and Amy Lee.  She also takes inspiration from the vocal powerhouses of the 80s, Pat Benetar and Joan Jett.  Riley also performs with several Philly-area theatre troupes at The Kimmel Center, Music Theater Philly, Upper Darby Summer Stage and her former school Girard Academic Music Program, and just wrapped up her 20th musical!  She is a Broadway triple threat, as she is an accomplished vocalist, dancer and actress.  Riley is a Vocal Major at The Philadelphia High School for Creative and Performing Arts (CAPA).  She is a female tenor, which is quite rare and considered a superpower in the vocal community, lol. Riley's other passion in life is playing mallet percussion (marimba, xylophone and vibraphone), and was the Middle School percussion section leader at GAMP.  She also plays percussion with the University of Pennsylvania Band, in their band camp and honor band programs.  She has had the privilege of playing at both Franklin Field and the Palestra, the holy grails of Ivy League sports.  Her backup future plan (just in case she is not the lead singer of a famous rock band (Modern Yesterday), on Broadway in multiple musicals and playing her marimba around the world, (all at the same time of course) is to attend UPenn and become a music/theatre critic, theatre director, and of course be a part of the Fighting Quaker Marching Band!




Seb may be young, but his natural musical ability surpasses his age.  Born in Philadelphia, this young guitarist is passionate about playing guitar and is clearly a natural born rocker.  Seb is fortunate to have a very supportive family, while still enjoying playing his favorite sports like basketball and boxing.  He started learning guitar when he was 7 years old with his School of Rock teacher Ty Asoudegan, then Rob Balducci.  His mentor is Luis Kalil of the Red Devil Vortex and his favorite guiar virtuoso is Paul Gilbert of Artist Works.  Seb wrote one solo album at the age of 12, and is the youngest endorsee of ESP guitars, Anatomy of Sound picks, and Headrush pedals. Being a part of the Top 10 finalists of the 2022 Dallas 10 under 20 guitar competition was his best achievement to date.  He was also featured in a Philadelphia Eagles commercial playing the  "Fly Eagles Fly" song in 2018 when they won the Super Bowl!




Victor Rosa was born into a family that includes several musicians including his father, grandfather and uncles, all of whom have played instruments and performed live. His father made it a point to keep all kinds of instruments in the house to ensure that his kids had access to anything that they were interested in playing. It was evident from infancy that the musical DNA was passed on to Victor, and the drums were clearly his instrument of choice. As an infant, there were times when he could only be amused or calmed when drum sticks were put in his hands, his high chair was moved in front of the electric drum set and he was allowed to play on the set.  At times, he would use his toys as a step stool to climb up onto a chair to play the drums.  As a toddler he used to mimic drum lines from the radio with his mouth and try to play them when he got home.
Victor’s parents decided to get him lessons at  5 years old to expand his talents. His instructors were amazed at his natural ability at such a young age. Over the years, Victor continued to refine his skills through practice and playing his favorite songs by ear.  He often called on his uncle, also a drummer, for advice and review of his play. His uncle has been instrumental in his development as a drummer, and continues to mentor him to this day.
In November of 2021 Victor was approached about joining a band of local teenagers called Modern Yesterday. It was always a dream of his to play on stage in a band, so he jumped at the opportunity. Since then, Victor has enjoyed playing live shows and showcasing his talents in festivals, competitions and special events all over the Delaware Valley. Victor continues to sell opportunities to improve his knowledge of theory, performance and different genres of music by attending camps, clinics, private lessons and schools, and he has built on what he's learned by joining the Kimmel Center's Youth Jazz Ensemble in 2022.
Victor continues to dream of bright lights and stardom, and yearns to play on the world's biggest stages someday. He has professed that he will work hard, continue to learn and practice until his goals and dreams are attained.




Alison has had a passion for music ever since she was young.  When she was six years old she began playing guitar and piano. Her love for music created wonderful opportunities such as getting accepted into Girard Academic Music Program and becoming the rhythym guitarist for Modern Yesterday.  Besides music, Alison loves fashion, spending time with her friends and rollerskating.

A few of his inspirations are The Ramones, The White Stripes, The Beatles and Operation Ivy, and his favorite bassists are John Paul Jones of Led Zeppelin and Matt McCall of Rancid.  Aidan is from Northeast Philly and is in 11th grade at Father Judge High School.
