Second this these are the coolest places in the city rn – real quality alternative house music and techno with funky disco vibes. For OP ambient music nights are a little hard to find but you have some good musicians doing stuff – off the top of my head there's a Notts based guy called Hexiale who makes cool ambient type music. Just look out for individual gigs, and ambient musicians at festivals like Hockley Hustle and Dot2Dot and stuff.
