There is a change to our coverage of classical CD releases. Since theartsdesk began in September 2009, we have been reviewing on a monthly basis. As of today we're switching to weekly and our round-up of the new classical albums will now appear every Saturday. To mark the change, we have a bumper helping, with Tansy Davies's new release taking a bow as our Disc of the Day. As for the rest, there's a Russian flavour – historic, idiomatic performances of Tchaikovsky symphonies, and exciting readings of Shostakovich piano concertos. Enjoy French sisters playing piano duets and a glorious Handel oratorio, and be soothed by the most alluring of sackbut recitals.

Imagine a special two-hour-plus resurrection of that wannabe extravaganza Stars in Their Eyes. "So, young maestro André de Ridder, who are you going to give us?" "Well, in addition to showing my special flair for contemporary music in Ligeti, I'm going to be Herbert von Karajan conducting On the Beautiful Blue Danube to a ballet of spacecraft." With another rigorously calibrated turn of the screw, it can only be the unique counterpoint of music, sounds, speech and silence with vision that is Stanley Kubrick's 2001.

Last night Murray Perahia played Bach, Beethoven, Brahms, Schumann and Chopin, and we heard, quite simply, Bach, Beethoven, Brahms, Schumann and Chopin. Nothing more need be said, if one follows the Cordelia principle to love, and be silent.

White-knuckle crescendos loom large in that greater-than-ever conductor Neeme  Järvi's spruce Indian summer. Short-term bursts were the chief payoff in tackling Dvořák's deceptively simple-seeming Serenade for Strings with a huge department on all too little rehearsal time, but they also helped to pave the way for the two big events in Shostakovich's Seventh Symphony: not just the infamous "invasion" sequence based on Ravel's Boléro, but above all the final slow burn. It was ultimately here that Järvi's mastery of the long, inward line showed us what creative conducting is all about.

Heavy-goods vehicles stacked with lamentations have been thundering through the Barbican Hall. Saturday's lugubrious Rachmaninov found a mid-20th-century counterpart last night in the tough elegies of Shostakovich's First Violin Concerto - apt for a dedication to those affected by the Japanese earthquake. And the tottering juggernaut of not-quite-great-but-living Russian composer Rodion Shchedrin still clogs the LSO's current season, fortunately in this case only to head a procession ending in the carnival float of what should have been Tchaikovsky's springiest symphony.

What is it about Rachmaninov's ghost-train masterpiece The Bells and death? The BBC Symphony Orchestra last played it under the great Russian conductor Yevgeny Svetlanov, who used it as a valedictory gesture knowing he had only weeks to live. Yesterday Semyon Bychkov measured out the funeral knell of its harrowing finale with surely some thoughts of his brother and fellow conductor Yakov Kreizberg, who died on 15 March at the age of 51.
