A response from an alum in the Chicago area

Great idea! I'm not really on the performance end of things so don't have any studio access. Two little things I can offer:

1) I do have a piano in my apartment. Perhaps we could arrange a schedule if someone wanted to practice.

2) Merit School of Music has a lot of practice rooms for their students. It might be worth investigating whether they offer them to students with no other space to practice. There must be music organizations in most of these locations that could be contacted for that purpose.

Good luck!
