RSS feeds for Songkick events

User calendar (upcoming gigs you're going to)

http://acousti.co/feeds/user/[username], e.g. http://acousti.co/feeds/user/mariomenti

Artist calendar (upcoming gigs for a given artist/band)

http://acousti.co/feeds/artist/[artistname], e.g. http://acousti.co/feeds/artist/Rolo Tomassi or http://acousti.co/feeds/artist/Mogwai or (you get the idea) http://acousti.co/feeds/artist/Bob Dylan
Note: if for some reason the above doesn't work and Songkick returns the wrong artist match, you can try and find the Songkick artist ID, and use a feed in this format: http://acousti.co/feeds/artistid/[songkick artist id]

Upcoming gigs for your tracked artists

http://acousti.co/feeds/upcoming/[username], e.g. http://acousti.co/feeds/upcoming/mariomenti

The above feed gives you the next 50 upcoming gigs of all your tracked artists, which on reflection probably isn't all that useful. What you probably want is a feed with newly added items, so you can get notified of new concerts by your tracked artists via RSS.
To do that, append "since=X", where "X" is the number of hours since new items were added. So:

http://acousti.co/feeds/upcoming/[username]?since=12, e.g. http://acousti.co/feeds/upcoming/mariomenti?since=12 gives you all events added in the last 12 hours
http://acousti.co/feeds/upcoming/[username]?since=24, e.g. http://acousti.co/feeds/upcoming/mariomenti?since=24 gives you all events added in the last 24 hours

Location (metro area) calendar

http://acousti.co/feeds/metro_area/[location], e.g. http://acousti.co/feeds/metro_area/Manchester or http://acousti.co/feeds/metro_area/Austin

Note I: if for some reason the above doesn't work and Songkick returns the wrong location match, you can try and find the Songkick metro_area ID, and use a feed in this format: http://acousti.co/feeds/metro_area_id/[songkick metro_area id]

Note II: because these feeds return ALL events for a given location, for popular Metro areas (e.g. London or New York), they will be a little slow in generating. You can restrict the result by dates in the following ways:

http:/acousti.co/feeds/metro_area/[location]?min_date=YYYY-MM-DD&max_date=YYYY-MM-DD to only return local events between min_date and max_date
http:/acousti.co/feeds/metro_area/[location]?days=X to only return local events for the upcoming X days
-> ... so http://acousti.co/feeds/metro_area/london?days=2 will return all Songkick events in London today & tomorrow

**NEW** Venue calendar

http://acousti.co/feeds/venue/[venue name], e.g. http://acousti.co/feeds/venue/Cargo or http://acousti.co/feeds/venue/Williamsburg Music Hall

Note I: if for some reason the above doesn't work and Songkick returns the wrong venue match, you can try and find the Songkick Venue ID, and use a feed in this format: http://acousti.co/feeds/venue_id/[songkick venue id]

Note II: You can restrict the results returned by dates in the following ways:

http:/acousti.co/feeds/venue/[venue name]?min_date=YYYY-MM-DD&max_date=YYYY-MM-DD to only return events at this venue between min_date and max_date
http:/acousti.co/feeds/venue/[venue name]?days=X to only return events at this venye for the upcoming X days
-> ... so http://acousti.co/feeds/venue/O2 Academy Brixton?days=7 will return all Songkick events at O2 Academy Brixton in the coming 7 days
