Worry filled my heart when the manager of Spring Offensive called me the day on the concert and started the conversation "hey, sorry, i have some bad news..". luckily the band just cancelled our second acoustic session, due to their strained voices.
and so they performed again in the Kulturclub Schon Schön (Mainz) this evening.
if you are not familiar with them, go to the next concert, also you should listen to our first acoustic session with them.
