pro tips from the producer of "call me maybe"
some cool riffs in this song specifically the bass rocking it at 5:41-6:11 and the guitar at 7:58-8:23. i would like to learn and build the finger speed for the latter technique. i want to say Tool used a very similar riff on 10000 days but i couldn't find it just skimming through.
