I like both of Brahms piano concertos, and the 1st has an enormously grand and impressive beginning. My favorite performance is by Arrau with Haitink.
I also consider the second concerto the greater of the two, and Gilels - yes, but with Reiner (RCA).It has a great monumental first movement, one of the greatest slow movements in all of Brahms and a slightly underwhelming finale. The second concerto is the greater work.
I love Gilels/Jochum but there are many great performances...
I was referring to the Gilels/Jochum recording of the 1st concerto. For the second... Dunno, I love both the Reiner and the Jochum performances. There's also a historical recording of Edwin Fischer with Furtwängler which I've always found really exciting.I also consider the second concerto the greater of the two, and Gilels - yes, but with Reiner (RCA).
