What can you say about a band whose frontman looks like Rivers Cuomo but sings like Robert Plant? It’s hard to conceptualize the sound of Philly trio, Busses, especially when they describe themselves as a classic rock/ punk/ progressive act – a combination that makes them seem as though they are in the throws of an identity crisis. But just because it’s difficult to transcribe their sound to words, it doesn’t mean they don’t rock (yes, that’s a double negative in the good way)! Their demos feature songs that are musical montages with funky bass riffs, soaring vocals, wandering drum beats and experimental electric guitar all strung together to create epic four minute tracks. The high point of their set for me will be the head-banging anthem, “Say It Again”, in which Nick Apice releases a climactic howl, “I will not forgive you,” accompanied by crashing cymbals raining down.
