One of the things I didn't like about the music scene in Amsterdam was that there were generally no opening bands at shows. Unlike in the US and UK where you typically have 3 bands on a bill, it seemed common practice in Amsterdam to buy a ticket to see an artist, only that artist would play, and then you'd leave. To my mind, this would have a negative impact on the local music scene because music is often discovered by big name artists bringing people in to hear the opening bands that play before them.
