Minor quibble - his name is spelled Lukather, not Lukarther. Wtf.
"It was incredible working with the full band in studio. I plugged my laptop into the protools session, as did Lukarther with his guitar & a few vocal mics. I’d play loops, chord progressions & beats & the guys would riff over the top. Lukarther even replayed one of my synth riffs on guitar which became the main hook in the chorus of the song. I walked away from that session with about 120 recordings of ideas & it took me about 3.5yrs & many revisits to fully realise the piece & pull it together."
