Like every kind of art form it's a matter of personal taste ... we use the generic term Salsa but there are of course so many variations within that term.
I know how difficult it can be to first understand what type of Salsa it is that you like and then, to find / source what your looking for. I agree with one of the previous post that a lot of what is on sale at the usual commercial outlets is tosh.
There is clearly a lot of good advise in the previous posts worth reading them all I'd say. I would agree also that initially a compilation CD is the best way to start to gain knowledge about the music, though if I were you I would ask advise about a well known compilation from someone who has been on the scene longer and who shares a similar view as you, as to what is good sounding Salsa.
At Fiesta Havana (Wednesday & Friday) We play a varied selection of Salsa covering most, if not all the variations ...
we cover all of the Countries that produce Salsa and play Salsa from the Younger Funkier Artists to the Older more Traditional.
I am always happy to give anyone the information they need about a particular band or track so they can buy it and also the place/s where they can source it.
So please don't be afraid to come and ask if you're in the Club !!!
