Raised On Radio sleeve

Journey • Raised On Radio

Released 21 April 1986 · 41st anniversary

Steve Perry took the reins as producer for this project, marking a significant shift in the band's creative process. The sessions were famously intense, resulting in a departure of longtime bassist Ross Valory and drummer Steve Smith mid-recording.

Polished studio production defines the sound here, leaning heavily into the sleek, radio-ready aesthetic of the mid-eighties. It serves as a final chapter for the band's classic era before they stepped away from the spotlight for several years.

ABBA sleeve

ABBA • ABBA

Released 21 April 1975 · 52nd anniversary

Global superstardom truly ignited with this 1975 release, which features the iconic opening riff of Mamma Mia and the melancholic perfection of SOS. These tracks proved that the group was far more than a one-hit wonder, cementing their status as masters of the pop hook.

Polished production techniques and a blend of rock energy with disco sensibilities define the record's signature sound. It captures the band transitioning from their folk-pop roots into the sophisticated, layered arrangements that would eventually define the entire decade.

Stray Cats sleeve

Stray Cats • Stray Cats

Released 21 April 1981 · 46th anniversary

Brian Setzer and his bandmates single-handedly dragged rockabilly out of the fifties and into the neon-soaked early eighties. They took the raw, dangerous energy of the original Sun Records era and injected it with a punk-rock attitude that made the music feel vital and rebellious all over again.

Recorded in London, the album captures a tight, stripped-down sound that relies on hollow-body guitars and stand-up bass rather than modern studio trickery. It remains a definitive document of the rockabilly revival scene, proving that vintage sounds could still dominate the airwaves in a new decade.

The Rumproller sleeve

Lee Morgan • The Rumproller

Released 21 April 1965 · 62nd anniversary

Hard bop at its absolute finest, featuring the signature trumpet tone that made this artist a legend. The title track is an infectious groove that perfectly encapsulates the mid-sixties jazz scene.

Every musician on this date is locked in, delivering solos that are as technical as they are soulful. It is the kind of record that makes you want to turn the volume up and just let it ride.

Check Your Head sleeve

Beastie Boys • Check Your Head

Released 21 April 1992 · 35th anniversary

The trio traded their signature party-rap persona for a gritty, self-produced sound that saw them picking up their own instruments again. This pivot transformed them from bratty provocateurs into a legitimate funk-rock powerhouse, blending live instrumentation with their classic crate-digging sensibilities.

Recorded at their own G-Son Studios in Los Angeles, the album captures a raw, garage-band energy that feels both loose and incredibly focused. It serves as a definitive document of the early nineties alternative scene, where the boundaries between hip-hop, punk, and jazz-funk were permanently blurred.

Gap Band IV sleeve

The Gap Band • Gap Band IV

Released 21 April 1982 · 45th anniversary

Synthesizers took center stage on this record, turning the group into pioneers of the electro-funk sound that defined the early eighties. The infectious, pulsing basslines and heavy drum machine programming found here became instant staples for dance floors and radio airwaves alike.

Production duties were handled by Lonnie Simmons, who crafted a polished, high-energy atmosphere that perfectly balanced soulful vocals with futuristic textures. This collection captures the transition from traditional R&B instrumentation to the sleek, electronic-driven aesthetic that dominated the decade.
