Translation:Even though we are listening to music we can read.
The second part of the sentence is the main clause. The obwohl... part is the subclause. In the subclause, the verb comes last. In the main clause, the verb comes second and all other verb parts come last. What you need to know that when it comes to counting the positions, the subclause counts as one element:
Obwohl wir Musik hören(last inside subclause), können(2. position) wir lesen(last position).
