October 24, 2025We had this band play at our home for a birthday party, and they were absolutely fantastic! Awesome music and good vibes. Our guests couldn’t stop talking about how talented they were and how much fun the night turned out to be. They played a perfect mix of songs, sounded incredible live, and were super easy to work with.

August 21, 2025Justin and his band, Big Logic & The Truth Serum, did an incredible job of entertaining our staff and guests. The entire band was very talented, with a wide range of music and diverse instrumental styles. This band can entertain any generation, as five generations were present at the event, and everyone was highly engaged by the performance of Big Logic and The Truth Serum. We invited them back after hearing them for the first time.
