There seems to really be no middle ground for Phish. You either love the band or hate it. In a career spanning more than 20 years, Phish never broke into mainstream appeal, but it has amassed a group of loyal, diehard fans, affectingly known as "phans." The concert antics — including the group singing the guitar solo to "Freebird" a capella, and the drummer wearing the same dress for 15 years — will keep you entertained, but the extended jams will keep you grooving. Even John McEnroe would be put into a relaxed, dance-filled trance during jams like "Bouncing Around the Room" and "Down With Disease."

Phish plays on Tuesday, July 17, at CMAC, 3355 Marvin Sands Drive, Canandaigua. 7 p.m. $55.15-$70.50. Cmacevents.com; phish.com.
