There is definitely a lot of forgettable fluff in the history of music. On the other hand, there are many great composers that deserve to be better known -- not particularly obscure, but at the same time without the kind of name recognition of the top tier, except to serious fans of classical music. C. F. Abel, Biber, Albicastro, Molter, Sances, Marais, Blavet, Leclair, Heinichen, Forqueray, Carbonelli, Carissimi, Cavalli, Bonporti, Busoni, Zelenka, Agricola, the Caccinis, Couperin, Gesualdo... Very hard to find concert programs featuring many of these!
