Macro to automatically insert rows between changes in data

Hi All,

I am extremely new to macros, but I think using one for this purpose would save me a great deal of time. I am using Excel 2010 on Windows 7. Here is an example of the data that i have in my worksheet:

El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- MISCELLANEOUS - 11501170
El Paso Live Events- STREETFEST - 11501179
El Paso Live Events- STREETFEST - 11501179
El Paso Live Events- STREETFEST - 11501179
El Paso Live Events- MEXICAN COOK OFF - 11501181
El Paso Live Events- MEXICAN COOK OFF - 11501181
El Paso Live Events- MEXICAN COOK OFF - 11501181

I would like to have the macro insert a row between each change in data. Is this possible and can anyone help with the code?

Thank you very much in advance for your help!
