Anton Bruckner’s symphonies, especially, 4, 7, 8 & 9. Bruckner loved big, loud brass choirs. Barenboim’s performance of the 4th with the Chicago Symphony on DG is a good one. The CSO has a great brass section and Barenboim unleashes them on that recording. The vinyl reissue on DG’s The Original Source series improves substantially on the original release, but it may be out of print by now.
Mahler's 2nd is my favorite symphony. It has everything in it.
