Be it Dr Dre and Eminem, Lil' Wayne and Drake or Jay Z and Kanye West, every artist in the industry started out with a mentor that showed them the way. These are their stories.
Here's a taster of what it was like on the rappers' Drake Vs. Lil Wayne tour.
Now Drake and Lil' Wayne's battle tour has ended, Weezy has given fans a sneak peek of what it was like on the road across America in the video for 'Grindin'.
The new track, taken from Lil' Wayne's 'Tha Carter V', features Drake, and the video sees the pair on stage and backstage during the tour.
The video was directed by DJ Scooby Doo and uses the Street Fighter-inspired imagery from the tour throughout.
'Tha Carter V' is one of a number of huge hip-hop albums due to be released before the end of 2014.
