Introvert vs Bjork - Joga Truly excellent orchestral progressive sounds from Introvert who takes on Bjork's 'Joga'. Already featured on James Zabiela's Radio 1 Essential Mix, 'Joga' comes in two versions, a sweeping progressive breaks workout on the A which builds towards a full vocal in the breakdown, while over on the flip, a straight up 4/4 version is what you get. Both are superb. Definitely a must have in my eyes.
