Would you like to sing blues

Hello,
We are a band who play blues, swing,
Soul  and more..and would like to find a native english speaker who wants to sing and swap spanish and catalan as well with us.
We play in Centro albareda en an av. Paralelo in bcn, green line. On saturdays
We are not profesional so we are not demanding high level.
Please if you think of it can be a good idea come and try. There is nothing to loose! Bye
