"Aztec" is a really nice rock flavored progression in the key of A. The chords are Bmi(add2) - D/F# - A, which constitutes a II -IV - I progression in Roman numerals.
I'm using my fingers again to articulate the voicings, but you can quite easily employ a pick to play this progression. If you like how it sounds, try transposing it into another key.
