You may want to decide first whether you want a recording featuring modern or original instruments. Since you mention Pinnock perhaps the latter is preferred. In that case I’d recommend the Smithsonian Institution’s box set featuring Albert Fuller leading Aston Magna. Beautiful analogue recording and widely available at your local used record shop for $5-6.
Need some help with Brandenburgs
Not so long ago, we got a new amp and I suddenly realized how bad my Brandenburg concertos sounded, so they are gone. I do have them on CDs, but it's not the same - I need records.
So I need help, the number of recordings of the Brandenburgs is overwhelming. I saw a recommendation for Trevor Pinnock with the European Brandenburg Ensemble, can anyone second this? Or give other recommendations? Benjamin Britten? It looks as if Yehudi Menuhin spent a large part of his career recording them, which seems obsessive.
Any help will be appreciated!
