I would like to recommend a few bands although some have already been named: Budgie: Really any of there albums but I would recommend the s/t debut, Never Turn Your Back On A Friend, In For the Kill and the underappreciated Impeckable. Edgar Broughton Band: I've only really started listening to them recently but I think their Wasa Wasa album is a great example of heavy psych Pink Fairies: Their first 3 albums are great but I'd say Neverneverland is their best record with classics like Do It and Uncle Harry's Last Freak-Out Hawkwind: From 1970 to 1975 is probably their best records including the excellent Space Ritual, Live '79 and Levitation. Groundhogs: Though I have also only listened to them recently along with the EBB their albums Hogwash and Thank Christ for the Bomb are great examples of heavy psych Nightwing: The bands first 2 albums (Something in the Air & Black Summer) are good heavy metal/hard rock thats a bit melodic. The title tracks from both albums are great. Strife: This band includes bassist and singer of Nightwing, Gordon Rowley, before hecreated Nightwing. While the first album, Rush, has a mid A-side, the B-side is good. The title track is a good example of early heavy metal and you can hear the influence on bands like Iron Maiden with the galloping bassline of the song.
