Are there any decent metal pubs in or around Oxford? Especially any that have live music.
For live music - have you tried Daily Info - their listings are pretty comprehensive for the area? https://www.dailyinfo.co.uk/ Look under gigs and comedy. An example is the Wheatsheaf Saturday - Hell's Addiction, Doomsday Outlaw, Broken Device, Reece Oxrox Rock / metalEdited: 10 November 2017, 04:37
pcw12kcox has already recommended Daily Info and the Wheatsheaf. You will also find occasional metal nights at The Cellar on Cornmarket, and a little bit further afield you might also find metal music occasionally at Fat Lils in Witney.
Nightshift magazine (available in print in record shops and online at http://www.nightshiftmag.co.uk/) is a great place to find listings and to find out about local bands, and http://www.metalgigs.co.uk/ is a general UK site - there are occasionally metal bands in the Bullingdon and the O2 on Cowley Rd too.
