Voices woven through staccato rhythms lead you to a narrow alley. Laughter flows from beneath a door. It opens to a kaleidoscope of sound and colour, led by an azmari singing a song of invitation. A waiter smiles as you glance in the book - you order a bira and some ocholoni. The day had started with a mountain top view of the Blue Nile and now the vibrant city nightlife takes you in.
