Now Booking for 2026 Events!
Mostly Harmless is a five-piece rock cover band delivering fun, danceable rock and roll to events throughout Philadelphia suburbs. Formed in 2022, the band came together when three co-workers joined forces with two new friends from the local music scene. United by their love of energetic, crowd-pleasing rock, they live for the moment the crowd starts moving and doesn’t stop!
With over 100 songs in rotation, our high-energy setlist spans decades – from The Beatles to The Foo Fighters – delivered with tight musicianship and rapid-fire transitions that keep the party going!
