This playlist consists of over 30 arrangements of Pictures, including over a dozen orchestrations, from Henry Wood, Leo Funtek, Maurice Ravel, Lucien Cailliet, Leopold Stokowski, Sergei Gorchakov (the RCA recording by Rickenbacher comes with colorful narrations), Lawrence Leonard (for piano and orchestra), Vladimir Ashkenazy (sounds much more Russian than Ravel's), Emile Naoumoff (for piano and orchestra), Leonard Slatkin (compendium version), Peter Breiner (for large orchestra). In addition, there's also arrangements for brass ensemble, piano trio, organ, trombone and piano, accordion, two accordions, cello and bass ensemble, wind orchestra, bassoon ensemble, piano and percussion, marimba duo... and yes, rock bands (ELP and metal band Mekong Delta). For solo piano, I included Kissin's performance of the original, plus Horowitz and Moiseiwitsch's own revised versions.
