Re: Lucha libre recommendations
Probably the best English-language lucha resource is the luchablog run by cubsfan, so you should bookmark that. In addition to the news and everything else, he uploads matches from the latest shows every week which you can download at that site or stream on his youtube channel which is (I can't post links) thecubsfan. Generally there is at least 10-15 matches per week to look forward to
Other good YT channels:
luchablog (the same site, but older content)
WarriorsX2000 (hasn't uploaded lately, but videos still working)
WarriorsX2000PPV (PPV / special shows)
TKD117 (about 2009 - 2011/12? onwards)
pakorusell (great fan-recorded independent shows)
Of course, effective use of google will point you in the right direction most of the time when it comes to finding specific shows or matches. If you want match recommendations wrestling KO is a good place, DEAN's match of the year thread on DVDVR has lots of lucha stuff usually, the luchablog has a MOTY table in the index. Older matches are generally harder to find than is the case with Japan or the US.
CMLL is the most prominent promotion in Mexico if not in ratings then in volume of televised content and events. They work the same venues every week more or less and hold lots of shows per week. Arena Mexico is their MSG, and they work the biggest shows of the week (and the year) there, usually on Tuesday and Fridays. They do smaller shows in Arena Guadalajara, Arena Puebla and Arena Coliseo but they are all televised. CMLL shows are usually broadcast anywhere from 4 to 8 days after they are held so when videos are uploaded they're usually 10 days behind or something like that. They don't follow the WWE/TNA formula with TV building up to monthly PPVs, but they do have special shows.
Homenaje a Dos Leyendas (Homage to Two Legends) takes place in March, Infierno en el Ring takes place in late June and involves a cage match (a rare thing in CMLL), they do an end of year show and then in September the big Anniversary show.
More important than titles (of which there are many, some of them ignored or infrequently defended) are matches with wagers (luchas de apuestas) like hair and especially masks. CMLL will usually save these matches for their biggest shows of the year. In general, CMLL books 3 vs 3 matches and sometimes 2 vs 2 on regular cards and nowadays 'lightning matches' (10 minutes or less I think, with one fall) in place of lengthy singles matches which are saved for either bigger cards or title matches.
Also, with the exception of lightning matches and torneo cibernetico, every match in CMLL (and Mexico in general) is two out of three falls, which has its pros and cons. Torneo cibernetico matches are hard to explain and follow at times. It's a chaotic elimination style match where wrestlers on each team can tag in following a specific order, C must tag in after B who must tag in after A etc. rather than A can choose who they want to tag in. There are also tournaments on and off the big shows with all sorts of different themes, some of which are decided with a torneo cibernetico. Fun!
AAA shows I believe get higher ratings in Mexico and run on a different format with less shows. More promos, more 'Americanised' story and character development, more run-ins and gimmick matches. They have big shows as well, often close to the date of CMLL's big shows. A lot of AAA wrestlers will work other independent shows between AAA tapings. Triplemania is their biggest show and is capable of drawing impressive crowds.
IWRG are also televised and loads of fun. There is a LOT of other televised or recorded stuff over any given week or month. I can't think of any specific show to start with, take a look at the stuff that's been recently uploaded and you should get an idea.
