Hi,
For my tastes, cellos are great and different.
The usage, however, differs, since I like how Bernard Herrman will use the cellos on his soundtracks, and Hitchcock films, and then there is the conventional orchestra styles ... which are sometimes interesting, but often ... just more melody on the same theme.
But there are some interesting uses of the cellos, in rock music that are special ... Esperanto Rock Orchestra did some nice things, including a Dance Macabre version with dueling cellos ... Ides of March (hit song Vehicle in late 60's) had a massive version of Eleanor Rigby with cellos ... and Esperanto also did even more later on an album called "Last Tango" in a couple of very theatrical pieces, including a version of Eleanor Rigby.
What is it with cellos and Eleanor Rigby? ... I have no idea!
My favorite, as an example, and it is one of those way out there in the middle of nowhere land, would be Wolfgang Tiepold and his free form excursions with Klaus Schulze ... pure improvisation at its best and sometimes just way too far out and neat and it creates some rather far out effects and moods.
All in all, it is a very nice instrument ... ALL of them are! ... that when they are accentuated in the right spot and piece, they are monumental in making that piece very special.
Favorite cello/bass player out there? ... David Darling ... catch him in the album called "Eos" with Terje Rypdal, for some of the prettiest chamber music for guitar and bass/cello ever done!
Congrats and enjoy the experience ... and hopefully it will help you tremendously ... and if I have a recomendation, think of the instrument as less of an accompanyment, but as a solo, and up front instrument instead of the background ... and yes ... that is my preference.
