I love this Karaoke place. I do not know what they do with the microphones but everyone sounds good there. 

The Amstel river is the main river of Amsterdam. Around 1200 they build a dam in the river and that was the birth of Amsterdam (or Amstelredamme as it was called back then). This dam is now situated under the Dam square, the central square of the city. If you bike from the old city center to the south along the banks of the Amstel, as I do every day on my way to my studio, the city opens up and gives way to a lot of space. If you follow the river it will take you out of town more quickly then you'd expect since it is surrounded by a green corridor that get's larger and greener as you exit the city. In less then half an hour bike trip from the old city you can find yourself in juicy green pastures between grazing cows and sheep. Only the airplanes heading in and out of Schiphol Airport will remind you that the city is near.

Where I buy most of my books and magazines for work. 

Under the city, the extraordinary Gesamtkunstwerk by Louis van Gasteren, Jan Sierhuis and others is located in Nieuwmarkt underground. This is one of the public artworks of the Seventies and early Eighties endangered due to station renovation on the Underground Eastline. At present there is a notice hanging at different spots on the wall: ‘‘This artwork has been temporally removed due to renovations”.

Rijksmuseum in all glory but the rather overlooked library is a must.
