High back up vocals & rythym guitar - Established Classic/Alt Rock Band

Established rock and roll band seeking a rythym guitar player (male or female) with strong ability to do high harmonies. Must be able to hit the high harmonies in songs by Boston, Van Halen, ACDC - don't bother if you can't. Have a great following and gigs booked. All members age 32-50 have families and day jobs, gig 1-3X a month. Will consider keyboard instead of rythym guitar. No drugs.
