Alder confirmed that she's ready for top billing, with her delicate, floated "himmlische" on smelling the rose being one of the most memorable moments.

Louise Alder, standing in at short notice for Teodora Gheorghiu, was a sparkling Sophie who won all hearts. EVENING STANDARD, Barry Millington, July 2014

 

(Alder's) bright and well-supported soprano was a constant reward. THE GUARDIAN, Martin Kettle, July 2014

 

It was the Sophie of Louise Alder, one year out of the Royal College of Music, who made me sit up with her sweet soprano and singing top notes.

THE TIMES, Geoff Brown, July 2014

 

The evening's other substitute was just as strong. Although Louise Alder is at the other end of her career to Hawlata, she made a confident fist of Sophie (having understudied the role at Glyndebourne). Nerves of steel ensured that her intonation was secure and her silvery top notes bloomed gloriously.

Strauss's formidable trio of women was completed by the Sophie of Louise Alder (a late replacement for Teodora Gheorghiu), with a warm, lyric soprano of great beauty, who brought much mischief to all the Act Two Ochs shenanigans. The three singers' Act Three 'Trio' fulfilled all those long-for expectations of Straussian soaring ecstasy.

Two stand-ins stood out. Louise Alder, who covered the role of Sophie at Glyndebourne, sang radiantly and acted the kooky, feisty youngster superbly, a revelatory Proms debut from a true homegrown talent of whom we'll hear a good deal more in the future. She makes her full Glyndebourne debut next season and that's something to watch out for. WHAT'S ON STAGE, Simon Thomas, July 2014
