From Sakari Oramo’s riveting Nielsen symphonies at the Barbican to Thomas Dausgaard kicking off the Proms’ Sibelius cycle, the two Nordic immortals are well served in their 150th birthday year. The BBC Scottish Symphony Orchestra, whose reins Dausgaard takes over from the great Donald Runnicles in 2016, may not have the sheer heft of the Berlin Philharmonic strings we heard earlier this year in Rattle’s Sibelius. But the Glasgow-based players get much deeper under the skin, and prove so much lighter on their feet when the Danish conductor takes flight.

Pairing Messiaen’s Turangalîla Symphony with John Foulds’ Three Mantras was a smart piece of programming: established modern classic and obscure novelty sharing an inspiration from Indian music and philosophy, and both perfectly designed for showing off a very fine orchestra to its best advantage.

The pulling power of the BBC Proms was in action last night, as a virtually full Royal Albert Hall settled down at 6.30pm, and braced itself for 22 testing minutes of restless, angular, unforgiving 1960s Boulez.The audience had been lured in by the gentler fare that was to come in the second half, but Boulez's Figures - Doubles - Prismes, under the taut control of its pulse by François-Xavier Roth, definitely left its mark.

Sir John Eliot Gardiner has made great play for years with the idea that Beethoven’s Fifth is a revolutionary symphony in not only musical but political terms. Accordingly the first bars were a call to arms, taking no heed of a restless Proms audience, or the Albert Hall’s generous acoustic, ploughing into and then through the argument with the joyful fury of a class war demo breaking police lines.

The England cricket team recently went through seven Test matches alternating winning and losing, the longest such sequence in the history of the game. Eric Whitacre managed a similar, and similarly frustrating, series of hits and misses in his Sunday matinee Prom of American music with the Royal Philharmonic Orchestra.

Yet another full Proms house sat down, and of course stood, for a rather strange six course meal which turned out not quite what the menu had led us to anticipate.

English choirs and early music ensembles have a bad reputation for stiffness, formality – nothing wrong with the music, just the presentation. But with this dramatic and Italianate Orfeo, John Eliot Gardiner, his English Baroque Soloists and Monteverdi Choir, reminded us just what is possible when you combine English musicianship with a looser, more instinctive presentation.

You never quite know whether a new work by James MacMillan is going to veer towards the masterly or the overblown. His magnificent chain of concertos has arguably yielded masterpieces, but the Third Symphony at the Proms in 2003 sounded like an unwieldy impersonation of the monumental. Twelve years have passed, and he’s shied off writing a Fourth until he felt he had something to say.

A weekend of extremes at the Proms took us from stark solo Bach on Saturday to the massed forces of the BBC Scottish Symphony Orchestra and the chorus of the Deutsche Oper Berlin, gathered under Donald Runnicles for Verdi’s Requiem. As a showcase for the kinds of repertoire the awkward Royal Albert Hall really does do well, it was pretty nigh perfect.

What would you expect of an ensemble performance played from memory? That the odd lapse, entirely understandable over the span of a 40-minute symphony, would be more than offset, perhaps, by gains in intimacy and flexibility as the players could look around and phrase together, respond to a conductor’s nudge and turn on a sixpence.
