Do you want recording quality or music? I 'll give you music...
But first, salsa is a Latin Caribbean phenomenom--started when mainly the Cubans and P/Ricans got together in NYC. It's hard to make a clear cut distinction, unless you *really* know the styles (Chicago salsa, Colombian salsa, etc.) In any instance, unless the music is straight from Cuba (due to their US-backed isolation) you'll usually find musicians from several countries in one group.
Celia Cruz is the "Queen of salsa". A good starter is her album with Wille Colón ("Only They Could Have Made This Album", Fania label). Machito has really good music with P/Rican singer Lalo Rodríguez). If you like Rubén González and Michel Camilo wait till you hear Eddie & Charlie Palmieri.
Straight Cuban, Adalberto Alvarez ("Una mulata en La Habana). Very intense. As for oldies, Cuarteto D'Aida. On RCA Classics.
For anyone who likes the songs of BVSC, La Corporación Latina blows them away by far, but none of their albums is on CD...
Try Willie Colón/Héctor Lavoe "Lo mato si no compra este disco." Van Alstine didn't like it played in his demo at the Chicago Audio Society--he cut me off, but that's another story! Maybe the music was too high energy for his equipment...salsa is extremely demanding on an audio rig. I use salsa albums to audition upgrades, tweaks and tuning.
Oscar de León is *the* best Venezuelan salsa man and his greatest hits album is a masterpiece...
The Cuban Nueva Trova genre is awesome but unless one knows Spanish it won't make sense. Try the latest of Liuba María Hevia ("Del verso a la mar."). Liuba María is a great singer and troubadour. Also Pablo Milanés (Cancionero). I saw Pablo live in San Juan and the show was nothing short of spectacular.
Well, this is a good starting point for you guys--I second Cachao and orquesta Aragón.
I want to add some Merengue--Olga Tañón's albums are very high energy and masterfully produced in Dominican Republic. She's from PR and transformed the genre by heavily emphasizing Spanish Gypsy elements. Her live album (Olga viva, viva Olga) won the US Grammy for best live album. I would recommend her greatest hits for starters...
OK, if you have a nearby Latin music store just go with list in hand and you'll be treated right. Otherwise look in the web...
