About Us

Based in San Francisco, California, the Cosmo Alleycats Band is a full-service private event band that performs regularly at weddings and private events throughout the Bay Area and Northern California.  We perform a potent mix of VINTAGE style dance music - including 1920s-1950s Jazz, Swing, Big Band, New Orleans Jazz, 60s R&B, Soul, and Motown - with a dynamic, soulful delivery. Our performance repertoire also extends to Klezmer music, Popular, and Contemporary music, all of which is adapted to our unique vintage sound and instrumentation.


The Cosmo Alleycats Band is a perfect choice for wedding celebrations of all sizes. We provide an elegant musical backdrop that won't interfere with luncheon/dinner conversation, while providing the right spirited energy for the occasion.  When the moment is right, we have the repertoire and approach that will get your guests to the dance floor as we raise the energy level and intensity to the level you feel is right for your vision and your chosen venue.


Our 5 and 6-piece band configurations are the most typical choices for wedding celebrations.  For smaller or acoustic weddings, our band can be reduced to 4-pieces, and for larger events, we can expand to 7 pieces. Our core instrumentation is: Piano/Keyboard/Hammond Organ - Upright Bass - Drums  -Saxophone/Clarinet/Flute  - Female Lead Singer -  Trumpet (optional).


We know that every wedding celebration is unique. When it comes time to coordinate with you and/or your event planner, you will find us adaptable and very easy-to-work-with. Our goal is to ensure a successful and memorable soundscape for your event and to give you the confidence - before, during, and after your event - that you have chosen the right band for your wedding.

  • Cosmo Alley Cats are FRICKEN AMAZING! Holy COW! Emily was absolutely wonderful to work with and was super responsive and helpful throughout the entire process. We got to do custom song choices that were not in their normal setlist which elevated the wedding even more. They knocked our choices right out of the park!!! The actual venue music was spectacular and their choice of music for every part of the wedding was spot on. Everything fit the mood perfectly. They were so good that many family and friends requested business cards and EVERYONE COULD NOT STOP RAVING ABOUT THEM!!! In addition, the band actually helped coordinate some of the wedding and queues to help keep things on track. HOLY CRAP, what a way to go above and beyond. THEY KILLED IT!!! Please hire them now or you'll regret it.
