Just in time for the long weekend (at least states-side), Fly Gypsy’s producer, one-man band, and DJ, Alexei, is releasing the first installment of his mixtape series that will highlight diverse music genres in a club-friendly format. Before delving into garifuna music, however, Alexei selects an obvious summer choice for the first installment — feel-good dance music. On “Alexei presents . . . The Club Fix,” Alexei mixes up hip hop and electro, dancehall and house in a continuous 75-min mix that will keep the energy high at any house party or cook-out. Alexei liberally swaps out vocals and instrumentals and retouches the tracks, turning out unpredictable mashups and remixes. The mixtape features Lil Wayne, Pitbull, Ludacris, David Guetta, Estelle, Busta Rhymes, Lauryn Hill, Nicki Minaj, LMFAO, Beenie Man, Jackson 5, Damian Marley and Nas, Janet Jackson, and many others. It also premieres the new Kanye West track “Diamonds.”
