Two new challenges test the artists' skills further - penning a club banger and performing with an orchestra. Hook King Deno visits the artists to mentor them on making a catchy song, then under the watchful eye of DJ Target, Krept and Konan, the artists must perform their club tunes to Ms Banks, who is listening from another room and judging their tracks on sound alone. Will any of the artists' anthems get the seal of approval from queen of club bangers? In challenge two, the artists dig deep to write about a surprising topic from their past. On performance day, Krept, Konan and Target deliver a shock surprise - the backing of a full orchestra. Can the artists rise to the occasion, or will they be drowned out by the power of the instruments? Wretch 32 also guests.
