Despite being in his 20s, Kendrick Lamar has a reputation for big verses, with singles like 'Swimming Pools (Drank)'
The 'Poetic Justice' rapper performed at the iTunes Festival at SXSW 2014.
The US rapper performed several hits from his studio album 'good kid, m.A.A.d city' and was on good form as he spoke to fans in the crowd.
"It's only right that we propose a toast to serenade the whole building. I want to propose this toast just cause ya'll be representing me from day one, supporting good music." Kendrick said, adding;
"I want every single one of ya'll to drink with me" before rounding off the one hour show with 'Swimming Pools (Drank).'
