Set a metronome at 110bpm. That‘s the second tempo that the drummer plays which is a 4/4 beat. If you then play 16th notes at 110bpm and accents every third note you are counting the quarter notes in 5/4 which is the first tempo that the guitar player starts the song with. If your familiar with polyrhythms it‘s 4:3 but instead of counting to 4 you count to 5. The tricky part is that you have to count to five 15 times (bars) before you land on the 1st beat again. Hope this makes sense. :
