Kendrick Lamar has jumped on his second cameo in as many months, following July’s appearance on ‘Nile’ (his contribution to Beyonce’s ‘The Lion King: The Gift’ record) with a tie-up on SiR’s ‘Hair Down’.

Speaking to Zane Lowe on Apple’s Beats 1, Kendrick’s label-mate said he “did exactly what he’s supposed to do, man…The song is about being confident in yourself, and he’s living his life and he definitely let it be known in that verse.”

SiR continued, describing to Lowe his love for Kendrick – “You should’ve seen me in a session when he was recording his verse, I’m sitting there like a kid. I was just trying to soak it all in, man. … I’ve had to adjust and get used to the thought that I’m supposed to be here. You know what I mean? So it’s a blessing and it’s definitely a lot to take in, but at the end of the day I think we got it done man, and I can’t wait to share more music and keep going.”
