Luke
Luke should play Dust in the wind, the whole song. Focus on the interlude and its Outro. Pay attention as well on the changes between the finger spacing on each one of the song’s parts.
Matias
Matias should practice Layla, the whole song. Focus on the intro and on the transition to its verse. He should also practice Jamaica Farewell on the Hal Leonard book. Pay attention on its rhythm and the syncopation.
