At 63, I'm too busy (both in the studio AND on stage) to worry about "getting too old to play music" . . . some of you may know about some of my credits from the late 60's thru the 80's as a musician and audio engineer in Los Angeles . . . but it's only been relatively recently, here in Mexico, that I've really "matured" as both musician and recording engineer . . .
Although I DO agree with you that a music "career" is best seen as an on-going journey (and that your music "will be the better for it.") and I AM proud of the fact that I play for "the love of playing" . . . I DO earn money, meet "friendly" youngish women and HAVE gained a bit of fame* with my group "El Haragan y Compania", but that's not the REASON that I play with them . . . I play with the group (since 1993!) because I like the variety of musical styles that we're able to play for our fans . . . the lyrics are VERY honest, reflecting the day-to-day realities of life in the barrio . . . and I like the guys . . .
I recieved my 1st Grammy nomination in 1970 as a member of the Don Ellis Orchestra . . . and many more over the years, both as a musician and as a recording engineer. Finally, in 2003, I won the 1st of my Grammys (and Latin Grammys) for work I did as an engineer . . . in 2006 my work (as engineer and as bassist) won both again . . . as of today, my work has won 3 Grammys and 5 Latin Grammys . . .
I guess what I'm trying to say is that, like many of the "old" jazz musicians (and B.B. King, too!), I want to continue playing music and making award-winning recordings until, literaly, I die . . .
*like has happened several times in Mexico City's Metro (subway system) . . . being recognized (in a city of more than 20 million people) and being asked where we're playing next . . .
