...These four albums on 3 CDs ("Jazz By Sun Ra", "Supersonic Jazz", "Jazz In Silhouette", and "The Futuristic Sounds Of Sun Ra") and bonus disk of singles are prime slabs of Sun Ra. Being of late-50s/early-60s vintage, the intricate, yet succinct, tunes mainly focus on acoustic horns/reeds and percussion, with an ethereal Martin Denny or Moondog production vibe. The real gem here for me is the bonus singles disc. It chronologically traces, through complete A and B-side couplets, Ra's evolution from Doo Wop(?!?) to the space-jazz for which he is known. I love hearing classic group harmonies float over an Arkestra-style beat on tracks like "Dreaming" and "Somebody's In Love"! In regards to packaging, the durable 4-CD plastic case is appreciated as it prevents scratching (unlike paper sleeves). The CDs themselves look cool, with vinyl-style groove artwork. Liner notes are indeed basic (no additional Sun Ra photos or art besides the cover image) but are thorough in regards to session information including recording/release dates, studios, and musicians. Only possible downside to the whole collection may be how the album "Supersonic Jazz" is split over disc one and two, but no biggie as the music flows well regardless. In conclusion, I really dig this release!
