Gustavo Dudamel and the LA Philharmonic accent the colours, rhythms, and passion of music by leading composers from Argentina in this invigorating evening at the Hollywood Bowl. Master of the Tango Nuevo, Astor Piazzolla’s four tangos feature on stage the dance company Tango Buenos Aires, known worldwide as the most authentic and uncompromising representative of the tango. Alberto Ginastera, one of the most important twentieth century classical composers of the Americas and Piazzolla´s first teacher, is also represented on this brand new release from C Major Entertainment, along with Lalo Schifrin, whom, beside his concert music, is the composer of the famous scores of Mission Impossible and Dirty Harry. His Concerto for Guitar and Orchestra, a world-premiere recording, is composed for Ángel Romero, an iconic master of the classical guitar.

In the course of their career, the Gryphon Trio has firmly established itself as one of the world's preeminent piano trios.The Los Angeles Times wrote This is a piano trio that plays with strength and unanimity… big, bold, almost orchestral performances. To celebrate their 25th anniversary, the trio offers one of their career's best recordings, the mesmerizing album The End of Flowers, which features works by the great composers Rebecca Clarke and Maurice Ravel, written at a time when World War I was on everyone's mind.

It's not easy in this eclectic age to juxtapose musical items that have never been in proximity before, but Canada's Gryphon Trio and soprano Patricia O'Callaghan manage to do so on this recording, which proclaims itself unlike any previous chamber music album. Even better than that, it's pretty much unlike any previous crossover album, although it has ancestors in the world of classical cabaret music where O'Callaghan has spent some of her time.

Listeners familiar with Scottish composer James MacMillan through such acclaimed works as The Confession of Isobel Gowdie (1990) or the Seven Last Words from the Cross (1993) may suspect that his music is usually somber and more than a little dour; indeed, his religious and politically themed pieces are quite earnest, and have given some the feeling that it might do MacMillan good to lighten up.

HK Gruber (b.1943) is one of the more refreshing of contemporary composers. His music is widely performed today, but since it takes time to become a household name many people have yet to make his acquaintance. Some background material is thus in order. This is how he presents himself on the Internet: 'Composer, conductor, chansionnier and double bass player HK Gruber (Vienna, 1943), is one of the most well-known and well-loved figures on the contemporary music scene, and yet he remains something of an enigma.

Telemann is said to have transformed traditional trio sonatas as composed and performed in Germany from esoteric music for virtuoso players into a considerably more popular form. I am not sure what "popular" means, but what we have here is music of the highest order, performed by a group of accomplished musicians. Admittedly, the sound of period instruments is not always to everyone's taste (including, at times, mine), but here they work well with the material and the result is on the musical mark.

Swedish clarinetist Martin Fröst is one of the world's top players, with a creamy, utterly consistent tone that is the envy of many a young player. It may be a surprise to see him take up Mozart's Clarinet Concerto in A major, K. 622, once again; he recorded it in the early 2000s with the Amsterdam Sinfonietta, along with its usual partner on disc, the Clarinet Quintet in A major, K. 581. But there are several new things this time around.

With a celebrated career encompassing five decades, Pinchas Zukerman reigns as one of today's most sought after and versatile musicians - violin and viola soloist, conductor, and chamber musician. He is renowned as a virtuoso, admired for the expressive lyricism of his playing, singular beauty of tone, and impeccable musicianship, which can be heard throughout his discography of over 100 albums.

Barbirolli made later recordings of all the works on this CD and these have become cornerstones of the catalogue. These are earlier recordings that he did with his own orchestra, the Halle, in the 1950s. To start with, the recording quality is pretty amazing. They were recorded on 35mm film tape rather than half inch recording tape by the Mercury team and have astonishing immediacy and amazingly lifelike. Barbirolli uses an organ in the finale of the Enigma Variations. The recording is a little bass heavy but this is a small caveat. For people who consider Barbirolli to be a bit indulgent as a conductor, these recordings may come as a surprise. The performances are very direct and nicely flowing. They therefore complement rather than compete with the later recordings. Of course, Barbirolli's later recording of the Cello Concerto with Jacqueline du Pre is a very famous and special rendition of the work. However, it is not without its detractors. Andre Navarra, by contrast, plays with golden tone. He plays gorgeously. Highly recommended.

One of the tastiest concoctions of the mid-'70s jazz-fusion era, Chain Reaction finds the Crusaders at the top of their form. The compositions are both accessible and memorable, and the playing is uniformly excellent. Guitarist Larry Carlton delivers some of his finest licks and funkified rhythm work. Wayne Henderson shows there is a place in fusion for the trombone. Wilton Felder does double duty, delivering smoking saxophone lines and funky bass riffs. Joe Sample's Fender Rhodes piano provides a solid chordal foundation and great solos. And the stickman, Stix Hooper, keeps the groove solid. The band employs a variety of rhythms and tempos, and gives the members plenty of room to strut their individual and collective stuff. In fact, "collective" may be the key word here, for this is the sound of a band, not just a group of guys thrown together for a recording session. Chain Reaction was one of the albums that helped lure young, rock and soul-oriented listeners over to check out the jazz side, and should not be missed by those interested in the more accessible, funky side of fusion.
