Hazell Dean’s Greatest Hits collects her Hi NRG and Synth-pop singles on Time Music International Limited — a compact CD that foregrounds her disco-rooted, high-tempo club anthems. Bright arpeggiated synths, driving four-on-the-floor beats and emphatic, melodic vocals push tracks toward peak-time intensity. With 208 listens from 14 listeners, it’s a tidy primer for DJs and fans of Hi NRG and Disco.
