As you can see, the old Improvisation Database has a new name : Improvised & Experimental Music Database with a brand new design and a lot of new features allowing everyone to add, edit or even delete entries. Posting comments is also possible.
To participate, you need to register to the site (in choosing Home > Register in the menu). It's safe and secure.
Maps from Google Maps are also available showing the cities that host improvised and/or experimental music venues. I hope it will help to book tours. To see the maps, you need to click on the Regions (Europe, USA, e.g.) *without* choosing a state or a country.
E-mail addresses are protected (you can have a look in the Source Code of a page to figure out how). So, don't be afraid to add them, they won't be grabbed by spam engines.
Don't hesitate to contact me (link below) if you encounter any problem and to make suggestions.
Have a nice day.
