Mac Miller first tasted success as part of the rap group, III Spoken. Miller soon went solo, signed with Rostrum Records and independently released his first album Blue Slide Park, in 2011. That album sold nearly 400,000 units. Miller was discovered by Rostrum Records thanks to his friendship with rapper Wiz Khalifa who had recently signed with the label president Benjy Grinberg. By releasing the album through an independent label, Miller and Rostrum earn significantly more money than they would have with a major label. After giving iTunes their 25% cut, Miller and Rostrum are able to split the entire remaining proceeds. Had he been signed with a major label, their cut would be much smaller.
