Rapper, poet & spoken word master, Mr Scroobius Pip, has got a podcast series called 'Distraction Pieces' and I highly recommend them!
His guests are really varied and the length of them (over an hour) is perfect, it feels like a really in-depth conversation that you're a part of.
The Zane Lowe one is particularly insightful and very inspirational - He's clearly a man who loves what he does and take every opportunity he can to be involved and to try new things. Super inspirational!
I'm still working my way through the podcasts myself, but I wanted to share the goodness - Subscribe and listen to them all right here:
As a bonus piece of inspiration, I really recommend Zane Lowe interviewing Jay Z (Found via him mentioning it in the above podcast with Scroobius Pip.) - It's another nice long-form thing (4 parts totalling an hour) and it's super insightful too; a really relaxed interview about Jay Z's life, work and everything else. It's great hearing about the time, effort and work put in by one of rap's legends.
