Easy ways to create rock progressions

Imagine u want to make a chord progression and play leads on it....

lets do it in the key of Am

most of the chord progrssions have a common format

Am Am Fmaj Dm Em
I VI IV V

in any key u can apply this rule and get the rock progression going..cool isnt it.

You can use Am pentatonic scale to jam over this progrssion.it will sound cool.You can add some extra notes if u have knowledge of major modes.:).
