Off to the DEMU showcase which is a new one for me. I've been messing around with blue diesels for decades, but this is the serious end of the game and there is a slight amount of trepidation. There is also a dress code. I asked my travelling companion if the venue was easy to find. 'No problem.' came the reply. 'Just follow the black clothing.' I understand there is a push from DEMU members to rid themselves of the subtitle of 'we are all goths'.
