Unless you’ve been living under a rock, you’re aware of the new 2,200-capacity Revolution Center coming to Garden City. The venue will celebrate its grand opening with a Wednesday-night concert from Eagles guitarist and singer Joe Walsh. This should be a memorable evening — and not just because Walsh is a little looser on stage as a solo performer. Recent shows have included solo hits (“Life’s Been Good,” “Rocky Mountain Way”), fan favorites (“I.L.B.T’s”), James Gang material (“Funk #49”) and Eagles hits (“In the City.”)
