Lutosławski: Concerto for Orchestra, Szymanowski: Three Fragments from Poems by Jan Kasprowicz Polish National Radio Symphony Orchestra/Alexander Liebreich, with Ewa Podleś (contralto) (Accentus Music)

It was as a violin soloist with the Scottish Chamber Orchestra that Joseph Swensen first appeared, in the mid-1980s, on the Scottish musical scene. He went on to become the orchestra’s principal conductor – a long and fruitful collaboration that lasted from 1996 to 2005.

Deep pain and sadness expressed through intense creative discipline aren’t qualities noted often enough in the music of Sergey Rachmaninov. Yet they’ve been consistently underlined, with rigour to match, in Vladimir Jurowski’s season-long “Inside Out” festival with his London Philharmonic Orchestra playing at a consistent white heat.

Be a soloist: take responsibility for yourself. These are not maxims often encountered in musical ensembles where unity of purpose and execution is valued, but they lie behind the philosophy and sheer style of Ensemble InterContemporain, which Pierre Boulez founded in his own image to show confidence in the necessity and vitality of a Modernism always under threat when an easy life and easy listening are so easily bought.

It took just two bars of Debussy's La plus que lente for Stephen Hough to transport the entire Royal Festival Hall to Paris. The nearest thing the French composer ever wrote to a café waltz – inspired by a gypsy band in a local hotel – this bewitching, louche yet elusive little piece might in other hands make a more suitable encore than opener.

If the thought of the annual trek to Hay-on-Wye for the literary festival in May fills you with as much gloom as it does me (and I don’t have to go as far as most of our readers), you might do worse than sample the town’s chamber music festival this weekend as a healthy change or at least a soothing antidote.

Malcolm Arnold: Symphonies 1-9 London Symphony Orchestra/Richard Hickox, BBC Philharmonic/Rumon Gamba (Chandos)

Time was when a Boulez concert with the LSO would have been directed by the man himself, but that is no longer possible. In Peter Eötvös they have the next best thing, a conductor who has known the man and his music for decades, whose listening ear is scarcely less acute and whose most recent appearance wth the LSO, in Lachenmann and Brahms with Maurizio Pollini, made quite miraculous music from intensive rehearsal.

Poised vibrantly enough between the buried-alive monotony of Philip Glass and the dynamic flights of John Adams, Steve Reich’s Three Tales deserves a special place in music-theatre history ("opera" it is not). Ironically, since it deals with the two-edged sword of the 20^th century’s major scientific developments, the video work with which the music interacts so brilliantly – by Reich’s former wife and long-term collaborator Beryl Korot – has been left looking a bit dated by rapid progress in that field since its 2002 premiere.

Gasps of surprise were heard across the country last month, when Richard Morrison on BBC Radio 3's "Building a Library" announced Daniel Barenboim and the Staatskapelle Berlin as his library choice for Elgar’s Second Symphony. That recommendation proved timely for the conductor and his orchestra, who yesterday completed their short London residency with the same symphony. The performance demonstrated a genuine intimacy with Elgar’s music.
