When Chester got the STP gig I was really happy… I instantly thought of how hard it would be for me to learn 30 Stone Temple Pilot songs. All those lyrics, I have such a hard time with that. I asked Chester how he learned all the songs so fast and he said:
‘I use four forms of learning.
1. Reading the lyrics.
2. Writing the lyrics down.
3 Singing along with the song (which builds muscular memory) and
4. Reciting them with my eyes closed!’
