Streaming the tracks at the moment - will probably be downloading the EP.
I'm very interested. I'm assuming you are the singer? If so, you have a very lovely voice, and trust me, it's no easy task to get me to like vocals - being a vocalist myself, it's probably the number one thing I pay attention to when listening to new bands, often a deciding factor as to whether I like them or not. You've got a very spotless baritone with a strong falsetto. Much akin to Stefan Larsen of Northern Portrait.
The melodies kept my interest rather well, also; my favorite was probably "Empires."
"Memory Song" is in my opinion the strongest song on the EP - very well done, I'd love to hear that someday with more polished production.
I'll be completely honest, the only thing I dislike about your band is the lyrics. This could just be due to my own preference, but I felt they left a bit to be desired - that they just meandered on at times and didn't really match the emotion with which you were singing. I feel if you had stronger lyrics, you could have some real hits on your hands. Regardless, as it is, I'm sure LISBON is due for a decent amount of success once you can make some more professional recordings
Good luck, and definitely keep us posted here on what's going on with you guys. I'm certainly interested and would be willing to promote you in the future, as my ensemble enjoys plugging the worthwhile new music that we like.
