New York house royalty Ralphi Rosario has got scores of classics in his back catalogue, and now Groovin have cherry-picked a couple that are more than worthy of a scrub up and repress. The record leads with 'An Instrumental Need', an absolute benchmark of piano house perfection which will instantly take a party to a truly positive place, and that's even before the vibes solo comes twinkling into earshot. On the B-side is 1997 stomper 'Take Me Up', which plays to Rosario's strength in whipping up a frenzy with some seriously stripped back disco heat and an anthemic vocal from Donna Blakely.
