Most piano duet arrangements were meant for the home rather than the concert hall. When you sight-read orchestral reductions at the piano, your physical involvement with the material “fills in” the missing instrumental color. Even with skillful four-hand “de-orchestrations” like Max Reger’s of the Bach Orchestral Suites, listeners run the risk of “registral fatigue”. In the main, the Speidel-Trenkner piano duo circumvents these limitations through canny pianistic means. In the C major Suite’s Forlane, for example, the oboe’s hornpipe-like melody bounces on a featherweight accompaniment.

Johann Paul von Westhoff (1656-1705) was one of the most brilliant members of the significant school of violinists that flourished in seventeenth-century Dresden. This impressive virtuoso, who was even applauded by Louis XIV at Versailles, wrote the very first compositions for unaccompanied violin, which of course foreshadow the later masterpieces of Johann Sebastian Bach. The programme recorded here includes some suites from his collection published in Dresden in 1696, as well as the suite that was printed in the Mercure galant of Paris in 1683, following his visit to Versailles.

Kees Bakels’ Vaughan Williams cycle is much better than many British critics like to admit. It’s strange, but you would think that it would be a source of pride for foreign musicians to conduct native composers like Vaughan Williams and Elgar. Unfortunately, what usually happens is that the “outsider” takes the music and promptly outclasses the home-grown talent. Such was the case with Slatkin’s Vaughan Williams cycle, which eclipsed the efforts of the likes of Boult and Handley, and it’s pretty much the case here.

This is the third in a series of posthumous albums of previously unreleased recordings by Randy California and Spirit, drawn from California's archives and assembled by Mick Skidmore. As Skidmore explains in his detailed liner notes, California put together an album called Blues From the Soul around 1995, and even copyrighted its contents; but later opted to use some of the material on the final album he released with Spirit, California Blues, prior to his accidental death by drowning in January 1997. Other tracks from the proposed album were culled for the first posthumous release, Cosmic Smile. Skidmore has included all 13 of the songs California had intended to use on his version of Blues From the Soul, though he has substituted alternate takes or live recordings of tracks already issued. Of course, the album also has been vastly expanded to include 35 selections for a running time of two-and-a-half hours. But the basic concept remains the same, and that is to present a collection of folk and blues recordings.

Born in Chelyabinsk in 1973, Lera Auerbach defected from the former Soviet Union to the United States while still in her teens, and she has since garnered much attention as both pianist and composer, notably in her recent work with Gidon Kremer. Written in 1999, Auerbach's 24 Preludes for Violin and Piano amply showcase her stylistic leanings and wide emotional range. Clearly, she's imbibed from the Shostakovich/Schnittke watering hole, as we hear in the frequent sparse textures in extreme registers, petulant dynamic shifts, obsessive pedal points, and caustic, folk-oriented tunes. Auerbach also has figured out what makes Astor Piazzolla tick, and manages to personalize his sultry harmonic idiom. The most interesting moments occur when the composer's original voice pushes her influences out of the way, as in the sudden, unexpected violin cadenza that immediately follows Prelude No. 15's unrelenting dance. This leads to a threnody that gradually dematerializes into a high-register mist, and before you know it, Prelude No. 16 is over. The Postlude and solo violin piece also typify the ease with which Auerbach communicates her ideas. Vadim Gluzman and Angela Yoffe push their collective virtuosity sky-high. Such big playing requires the larger-than-life engineering BIS provides.

Ackles' self-titled debut LP introduced a singer/songwriter quirky even by the standards of Elektra records, possibly the most adventurous independent label of the 1960s. Ackles was a pretty anomalous artist of his time, with a low, grumbling voice that was uncommercial but expressive, and similar to Randy Newman's. As a composer, Ackles bore some similarities to Newman, as well in his downbeat eccentricity and mixture of elements from pop, folk, and theatrical music. All the same, this impressive maiden outing stands on its own, though comparisons to Brecht/Weill (in the songwriting and occasional circus-like tunes) and Tim Buckley (in the arrangements and phrasing) hold to some degree too. This is certainly his most rock-oriented record, courtesy of the typically tasteful, imaginative Elektra arrangements, particularly with Michael Fonfara's celestial organ and the ethereal guitar riffs (which, again, recall those heard on Buckley's early albums).

As disco became an important part of the international music business, European producers began working in exotic flavors into the disco beat to create unique and competitive recordings. A good example of this trend is Santa Esmeralda, a Spanish-themed studio group that wove elements of flamenco, salsa, and other Latin musical styles into its Euro-disco sound. Although the group's sound was about as genuinely Spanish as Herb Alpert & the Tijuana Brass (Santa Esmeralda was the brainchild of French record producers), the result was a crossover success that spawned several club-favorite albums and a notable pop hit in the band's Latinized cover of "Don't Let Me Be Misunderstood".
