For any professional looking to build a bulletproof music library, the Mastermix Classic Cuts Volume 1-100 is the ultimate foundation.
The Mastermix Classic Cuts series stands as the definitive library for professional DJs, radio programmers, and serious music collectors. Spanning from Volume 1 to Volume 100, this massive collection represents a chronological and genre-defying journey through the history of popular music. It was designed with a singular purpose: to provide high-quality, unmixed, and radio-edit versions of the most essential tracks ever recorded. Mastermix Classic Cuts volume 1 - 100 -complete...
Technical quality is another reason this set is highly coveted. Before digital downloads were ubiquitous, finding clean, remastered versions of certain rarities was difficult. Mastermix sourced the best possible masters, ensuring that whether you were playing a track from 1954 or 1999, the audio levels and clarity remained consistent for professional PA systems. The "Complete" 1-100 set serves as a time capsule
The scope of the first 100 volumes is staggering. It covers the birth of Rock 'n' Roll in the 50s, the British Invasion and Motown sounds of the 60s, the Disco and Punk explosions of the 70s, the Synth-Pop and New Wave era of the 80s, and the Britpop and Dance anthems of the 90s. Each volume is typically themed or era-specific, allowing a DJ to quickly navigate to "60s Floorfillers," "70s Glam Rock," or "90s Girl Power." It is more than just a music collection;
For decades, Mastermix has been the gold standard in the DJ industry. Unlike their "Issue" series which features megamixes and remixes, the Classic Cuts line focuses on the "original" versions. This makes the 1-100 collection an indispensable tool for mobile DJs who need the "right" version of a song to fill a dancefloor, rather than a niche club remix.
