From good old rock and psych rock to melancholic, country(ish) rock, this album shows great diversity in its track list. You can tell that they poured all their love and passion into this little gem, which also shows in the lyrics, ranging from some upbeat and some weird and creepy songs to ones like "Long Lonely Night", which just gives me this yearning feeling (could be the harmonica, I guess).
All in all, one of the greatest rock albums I've listened to in a long time. Highly recommended.
