Pie chart could very easily have been Kerrang pandering to fans and doing baseless speculation.
@Qwerty18 not the way LP did it. That's what the person you quoted was referring to.
Now, let's not blow this interview out of proportion. We're not getting Hybrid Theory 3 (not that anyone said we would). "More guitars", considering what LP has been doing the past few years, probably just means "more prominent guitars" because ATS was covered in guitars, but in a subtle, quieter fashion that added to the soundscapes the album built.
I think what Chester is trying to convey is similar to what Nine Inch Nails did in regards to The Fragile and With Teeth - The Fragile was an epic two-disc, two-plus-hour masterpiece with numerous overarching themes, and a loose storyline throughout the album, tied together by repeating motifs and complex soundscapes. With Teeth, on the other hand, was most definitely an album of songs - some of them shared themes, sure, but there wasn't an overarching theme that tied it all together. The songs all stood on their own.
What I was most interested in was Chester's mentions of the lyrical content; glimmers of hope, of positivity. That's something I'm not used to seeing with LP. That's what I'm definitely most interested to hear more about.
