I tend to write stuff like this a lot:
(dialogue)
They remained silent for a while. “Where is my mind” by Pixies was now playing in the background. Eri stared at her palm beneath the Heineken neon sign next to her. Its light made her skin look greenish, like that of a traveler from a far away civilization.
(dialogue)
(dialogue)
The room fell silent. An ambulance could be heard at the distance. Its sound grew louder and louder, then gradually faded into the silence of the night.
(dialogue)
The reason I added the bolded part was to make the transition between dialogue and action smoother. Are they unnecessary? Would it be better if I write this instead:
(dialogue)
The background song changed to “Where is my mind” by Pixies. Eri stared at her palm beneath the Heineken neon sign next to her. Its light made her skin look greenish, like that of a traveler from a far away civilization.
(dialogue)
(dialogue)
The siren of an ambulance blared in the distance. Its sound grew louder and louder, then gradually faded into the silence of the night.
(dialogue)
Maybe the actions imply (or give the feeling) that there is a pause in the dialogue?
