Any racquetball players and musicians here in Medellin?

Hola todos.  After Buenos Aires, Mendoza, Santiago, and Bucaramanga, I am now in Medellin until the end of February.  Wasn't simple but I did find the single gym in all of Buenos Aires with two racquetball courts, aka conchas.  So far it looks like Club Medellin Ejecutivos may be the only such venue here, and they seem fairly inaccessible and unreceptive to returning my calls.  Maybe I need the Mayor to refer me?  Anyway, anyone play racquetball and know where that can happen here in Medellin?  I have a squash court in my apt building in El Poblado so I suppose that will do in a pinch, though I thought I'd give this a shot.  (Two really bad puns intended). 

In addition to playing racquetball for over 25 years, I play guitar and bass guitar, even sing a little, and did so with a band for years.  If there are any musicians here who have access to equipment and would like to play please let me know.  BTW:  I  suspect that if someone had a venue, organized the local musicians who undoubtedly live here, got them up to speed on 30 or 40 popular American rock tunes, you'd probably make a fortune.

Just thought I'd check things out here and see what you all might know.  Thanks for listening.  Tom
