Alfred Schnittke's Second Concerto Grosso is a different creature than his First. While the 1977 Concerto Grosso No. 1 for 2 Violins, Strings and Keyboards is a lithe, vicious, often comical work, the Second, finished five years later, is a weightier affair. The soloists are now violin and cello; the Baroque band is now a full orchestra with electric guitar, drum kit, and brake drum; there are four large movements rather than six smaller ones; the entire work is imbued with an air of sincere tragedy, albeit with mud on its shoes. Schnittke dedicated the work to its premiere soloists, husband-and-wife duo Oleg Kagan (violin) and Natalia Gutman (cello); famed for their flawless ensemble, the couple inspired in Schnittke a musical air of companionship – a single soul in two instruments.

Live Classics’ Natalia Gutman “Portrait” series continues with a second volume documenting the cellist’s work from her early career up to the present. A 1967 German radio broadcast of the Debussy Cello Sonata stands out for Gutman’s warm, expansive tone and strong, fluid support from pianist Alexei Nassedkin. A few moments of uncertain intonation and less-than-centered articulation in the second movement’s opening pizzicatos are a small price to pay for fine overall ensemble values. Gutman shines in the declamatory, slow-motion passages that dominate the outer movements of Schnittke’s First Cello Sonata, and throws herself head first into the central Presto’s roller-coaster arpeggios and ruthless clusters. A gripping performance, this: every bit as authoritative as Alexander Ivashkin’s with the composer’s widow Irina Scnittke at the piano. She’s a more sensitive colorist than Gutman’s solid yet comparatively monochrome Vassily Lobanov.

In all three quartets the Borodin play with an easy authority and what seems to be perfect style. There are no obvious interpretative quirks, there's nothing showy to get between the music and the listener, and it is evident that these musicians are thoroughly immersed in the authentic Russian tradition of playing Tchaikovsky's music. Technically and tonally they are first rate, and they combine well with the two excellent extra players in Souvenir de Florence.
