One reason why you probably haven't heard it live is because it requires a huge orchestra to play it. Berlioz, as you may or may not know, was a master of orchestration.
His "Requiem" is a beautiful piece, but as I mentioned the orchestration is huge. I got the following information from Wikipedia:
The Requiem is scored for a very large orchestra, four brass bands, and chorus placed throughout the hall:
Woodwinds
4 Flutes
2 Oboes
2 English horns
4 Clarinets in B-flat
8 Bassoons
Brass
12 Horns in C, E-flat
4 Cornets in B-flat
4 Tubas
Percussion
16 Timpani (10 players)
2 Bass Drums
10 pairs of Cymbals
4 Tam-tams
4 Brass Choirs
Choir 1 to the North
4 Cornets
4 Trombones
2 Tubas
Choir 2 to the East
4 Trumpets
4 Trombones
Choir 3 to the West
4 Trumpets
4 Trombones
Choir 4 to the South
4 Trumpets
4 Trombones
4 Ophicleides (usually substituted by Tubas)
Voices
Chorus:
80 Sopranos
60 Tenors
70 Basses
Tenor solo
Strings
25 Violin I
25 Violin II
20 Violas
20 Violoncellos
18 Double Basses
I would check out Colin Davis' take on this on the Philips label with the London Symphony and also check out Charles Munch's take with the Boston Symphony Orch. Both are amazing interpretations and should be heard by everyone who's interested in Berlioz.
