The Pons (formally Lalaland). They're led by Tommy Mazzi and are known for their stick-in-your-brain melodies and big hooks. Mazzi's songs reminded me of alt-rockers from the late 80's and early 90's, like Paul Westerberg, Matthew Sweet, and Soul Asylum, but better. The lyrics are slightly dark but have a sense of redemption. The set included some noisy forays with Mazzi adopting a gunslinger mentality with his ax. Before I knew it they were announcing their last song. I was disappointed they didn't play longer since they were the best act of the night.
