The four pie shaped "buildings" left of center
are the new Music Wing at Grinnell College.
The lower one is the Ethno Wing which houses the Javanese Music (Gamelan) and Dance.
The next one clockwise is the Early Music (Collegium) rehearsal room and studio.
The rehearsal room for the Jazz Band, Orchestra and Choirs is the third room.
The new 350 seat Recital Hall is the last "building".
You are looking South-Southeast. The area to the right of center is the New Art Gallery with the new art wing directly behind it. The East edge of the the Art Gallery (with the 4 skylights) runs basically North to South with North towards the bottom and South towards the top.
