I come mainly to learn trumpet and musical techniques and usually to learn from others.
My background is in composing, conducting and playing woodwinds. I've got tons of experience in those. I studied trumpet and played in Lab Bands at UNT as a student and played trumpet in the military for one tour in and in soul bands.
So, most of my experience, and I can share in those areas, are as stated, while trumpet experience was as a professional, too, but much less than the other areas.
I do think the TM crowd is less hard-core than the TH one, but I still see the Lounge as a fleeting diversion, not as a replacement for musical/trumpet subjects.
