When Bakhtiyar Mamedov adopted the name Jah Khalib and released his debut EP in 2015, the Kazakh rapper made a huge first impression. Thanks to his deep, imposing voice, his songs can range from proudly assertive spoken lyricss to smooth and even tender sung vocals underpinned by appealing melodies. A prime example of the latter is the catchy "Summer Time", where a languid tempo, jangling acoustic guitar and sung chorus invoke a carefree feeling, while Khalib's insistent rap lends a harder edge.
