Hello, yes I hail from the Wirral, over the water from Liverpool & spent my formative years over the 'pool. All opinion this, no doubt someone will have a different one. lots of good nights on. Chibuku shake shake & circus being the biggest i think (although i now live in manchester so may be corrected here). Both normally take place at the masquerade, a decent good size venue - digweed is playing end of feb. Chibuku do however do all nighters at nation (former home of cream) which is a seriously good venue & I have had many top nights there. Other smaller nights include freeze and aztec, both good quality house & techno. Crowds are usually very good, liverpool is lucky in a way that it has its own scally off shoot of house, called scousehouse (I kid you not), so all the mongos tend to congregate at specially designed mongo nights! also voodoo is a techno night, but really hard techno usually if thats yer thing.
Do not go to wrongdevous. awfull pastiche of a student night. or the 051 or the state. pikey central.
In summary i would recommend picking a chibuku all nighter as it has a variety usually, d&b, house/electro & techno in diff rooms.let me know if you have any other queries
